Carbon neutrality is an important goal for humanity . As an eco‐friendly technology, electrocatalytic clean energy conversion technology has emerged in the 21st century. Currently, metal‐organic framework (MOF)‐based electrocatalysis, including oxygen reduction reaction (ORR), oxygen evolution reaction (OER), hydrogen evolution reaction (HER), hydrogen oxidation reaction (HOR), carbon dioxide reduction...
Relapse and unresectability have become the main obstacle for further improving hepatocellular carcinoma (HCC) treatment effect. Currently, single therapy for HCC in clinical practice is limited by postoperative recurrence, intraoperative blood loss and poor patient outcomes. Multidisciplinary therapy has been recognized as the key to improving the long‐term survival rate for HCC. However, the clinical...
Heterogeneous crystalline‐amorphous structures, with tunable electronic structures and morphology, hold immense promise as catalysts for lithium‐oxygen batteries (LOBs). Herein, a nanotube network constructed by crystalline nickel sulfide/amorphous nickel phosphate (NiS/NiPO) heterostructure is prepared on Ni foam through the sulfurization of the precursor generated hydrothermally. Used as cathodes,...
This work reports a metal–organic framework (MOF) with less‐coordinated copper dimers, which displays excellent electrochemical CO2 reduction (eCO2RR) performance with an advantageous current density of 0.9 A cm−2 and a high Faradaic efficiency of 71% to C2 products. In comparison with MOF with Cu monomers that are present as Cu1O4 with a coordination number of 3.8 ± 0.2, Cu dimers exist as O3Cu1...
Macroscopic 3D porous materials are ideal solar evaporators for water purification. However, the limited sunlight intensity and penetrating depth during solar‐driven evaporation cannot prevent the biofouling formation by photothermal effect, thus leading to the deterioration of evaporation rate. Herein, a magnetic heating strategy is reported for anti‐biofouling solar steam generation based on a magnetic...
Halide Crystals
In article number 2205981, Ken‐Tsung Wong, Hao‐Wu Lin, and co‐workers demonstrate highly efficient and green emissive manganese halide crystals showing a notable absolute photoluminescence quantum yield ≈ 94% and an unprecedented thermal quenching resistance from 4 to 623 K. The crystals find their applications in phosphor‐converted light emitting diodes, organic light emitting diodes...
The phosphor‐converted light‐emitting diode (PC‐LED) has become an indispensable solid‐state lighting and display technologies in the modern society. Nevertheless, the use of scarce rare‐earth elements and the thermal quenching (TQ) behavior are still two most crucial issues yet to be solved. Here, this work successfully demonstrates a highly efficient and thermally stable green emissive MnI2(XanPO)...
Solar‐driven production of hydrogen peroxide (H2O2), as an important industrial chemical oxidant with an extensive range of applications, from oxygen reduction is a sustainable alternative to mainstream anthraquinone oxidation and direct hydrogenation of dioxygen methods. The efficiency of solar to hydrogen peroxide over semiconductor‐based photocatalysts is still largely limited by the narrow light...
A small‐scale standalone device of nitrogen (N2) splitting holds great promise for producing ammonia (NH3) in a decentralized manner as the compensation or replacement of centralized Haber–Bosch process. However, the design of such a device has been impeded by sluggish kinetics of its half reactions, i.e., cathodic N2 reduction reaction (NRR) and anodic oxygen evolution reaction (OER). Here, it is...
Organic electrode materials with the advantages of renewability, environment‐friendliness, low cost, and high capacity have received widespread attention in recent years for sodium‐ion batteries. However, small molecular organic materials suffer from issues such as low conductivity and the high dissolution rate in electrolytes. Herein, a phthalocyanine derivative (TPcDS) with a large non‐localized...
An unprecedented microwave‐based strategy is developed to facilitate solid‐phase, instantaneous delamination and decomposition of graphite fluoride (GF) into few‐layer, partially fluorinated graphene. The shock reaction occurs (and completes in few seconds) under microwave irradiation upon exposing GF to either “microwave‐induced plasma” generated in vacuum or “catalyst effect” caused by intense sparking...
Rechargeable aprotic lithium (Li)–O2 batteries with high theoretical energy densities are regarded as promising next‐generation energy storage devices and have attracted considerable interest recently. However, these batteries still suffer from many critical issues, such as low capacity, poor cycle life, and low round‐trip efficiency, rendering the practical application of these batteries rather sluggish...
Surface modifications of plasmonic nanoparticles with metal adsorbates are essential in applications such as plasmonic sensing, plasmon‐enhanced photocatalysis, etc., where spectral broadening is usually observed. A single particle study is presented on plasmon damping by adsorption of platinum (Pt) clusters. Single particle dark‐field spectroscopy is employed to measure exactly the same gold nanorod...
