Selective hydrogenation of nitrostyrenes is a great challenge due to the competitive activation of the nitro groups (─NO2) and carbon–carbon (C═C) double bonds. Photocatalysis has emerged as an alternative to thermocatalysis for the selective hydrogenation reaction, bypassing the precious metal costs and harsh conditions. Herein, two crystalline phases of layered ternary sulfide Cu2WS4, that is, body‐centered...
Anti‐site defective potassium poly(heptazine imide) (KPHI) with the central nitrogen atoms partially replaced by graphitic carbon atoms in the flawed heptazine rings is prepared by direct ionothermal treatment of the rationally designed supramolecular complex in KSCN salt molten. Compared to the KPHIs without the anti‐site defect, the anti‐site defective KPHI demonstrates significantly improved photocatalytic...
Semiconducting nanocrystals have attracted world‐wide research interest in artificial photosynthesis due to their appealing properties and enticing potentials in converting solar energy into valuable chemicals. Compared to 0D nanoparticles, 1D nanorods afford long‐distance charge carriers separation and extended charge carriers lifetime due to the release of quantum confinement in axial direction...
Low‐dimensional materials serving as photocatalysts favor providing abundant unsaturated active sites and shortening the charge transport distance, but the high surface energy readily causes the aggregation that limits their application. Herein, it is demonstrated that 2D covalent organic framework (COF) TpBD nanosheets are effective in the dispersion and stabilization of 0D Ni(OH)2. The COF precursor...
Herein, a facile strategy is illustrated to develop pyrolysis‐free out‐of‐plane coordinated single atomic sites‐based M‐POP via a one‐pot Friedel Craft acylation route followed by a post‐synthetic metalation. The optimized geometry of the Co@BiPy‐POP clearly reveals the presence of out‐of‐plane Co‐single atomic sites in the porous backbone. This novel photopolymer Co@BiPy‐POP shows extensive π‐conjugations...
Advanced Photocatalytic Materials
Developing next‐generation photocatalytic materials contributes to scientific advances in environmental and energy catalysis. This paper presents the fundamental theory, structure–performance relationship, and catalytic advantages of hollow nanoreactors (HoNRs) employed as novel‐type of advanced photocatalysts, which may provide a prospective guidance for the future...
Hollow nanoreactors (HoNRs) have regarded as an attractive catalytic material for photocatalysis due to their exceptional capabilities in enhancing light harvesting, facilitating charge separation and transfer, and optimizing surface reactions. Developing novel HoNRs offers new options to realize controllable catalytic behavior. However, the catalytic mechanism of photocatalysis occurring in HoNRs...
Crystalline carbon nitride (CCN), derived from amorphous polymeric CN, is considered as a new generation of metal‐free photocatalyst because of its high crystallinity. In order to further promote the photocatalytic performance of CCN, p‐type MnO nanoparticles are in situ synthesized and merged with n‐type CCN through a one‐pot process to form p–n heterojunction. The formed interfacial electric field...
The free electron transfer between cocatalyst and photocatalyst has a great effect on the bonding strength between the active site and adsorbed hydrogen atom (Hads), but there is still a lack of effective means to purposely manipulate the electron transfer in a beneficial direction of H adsorption/desorption activity. Herein, when ReSx cocatalyst is loaded on TiO2 surface, a spontaneous free‐electron...
The weak electronic interaction at metal‐photocatalyst heterointerfaces often compromises solar‐to‐fuel performance. Here, a trifunctional Schottky junction, involving chemically stabilized ultrafine platinum nanoparticles (Pt NPs, ≈3 nm in diameter) on graphitic carbon nitride nanosheets (CNs) is proposed. The Pt–CN electronic interaction induces a 1.5% lattice compressive strain in Pt NPs and maintains...
Hierarchical self‐assembly of 2D metal‒organic layers (MOLs) for the construction of advanced functional materials have witnessed considerable interest, due to the increasing atomic utilizations and well‐defined atom‒property relationship. However, the construction of atomically precise MOLs with mono‐/few‐layered thickness through hierarchical self‐assembly process remains a challenge, mostly because...

In article number 2311045, Nikos Tagmatarchis and co‐workers showcase a novel photocatalytic approach for transforming transition metal dichalcogenides (TMDs). In the groundbreaking methodology, tetrabutylammonium decatungstate is employed as photocatalyst together with aldehydes to acylate semiconducting TMDs. The catalytic approach introduces principles of atom economy...
Transition metal dichalcogenides (TMDs) are promising 2D nanomaterials for diverse applications, but their intrinsic chemical inertness hinders their modification. Herein, a novel approach is presented for the photocatalytic acylation of 2H‐MoS2 and 2H‐MoSe2, utilizing tetrabutyl ammonium decatungstate ((nBu4N)4W10O32) polyoxometalate complex as a catalyst and a conventional halogen lamp as a source...
Sustainable and scalable solar‐energy‐driven CO2 conversion into fuels requires earth‐abundant and stable photocatalysts. In this work, a defective Nb2C MXene as a cocatalyst and TiO2 microspheres as photo‐absorbers, constructed via a coulombic force‐driven self‐assembly, is synthesized. Such photocatalyst, at an optimized loading of defective Nb2C MXene (5% def‐Nb2C/TiO2), exhibits a CH4 production...
