The crystalline/amorphous heterophase nanostructures are promising functional materials for biomedicals, catalysis, energy conversion, and storage. Despite great progress is achieved, facile synthesis of crystalline metal/amorphous multinary metal oxides nanohybrids remains challenging, and their electrocatalytic oxygen evolution reaction (OER) performance along with the catalytic mechanism are not...
Transition metal nitrides (TMNs) nanostructures possess distinctive electronic, optical, and catalytic properties, showing great promise to apply in clean energy, optoelectronics, and catalysis fields. Nonetheless, phase‐regulation of NiFe‐bimetallic nitrides nanocrystals or nanohybrid architectures confronts challenges and their electrocatalytic overall water splitting (OWS) performances are underexplored...
The development of hydrogen sensors is of paramount importance for timely leak detection and remains a crucial unmet need. Palladium‐based materials, well known as hydrogen sensors, still suffer from poisoning and deactivation. Here, a hybrid hydrogen sensor consisting of a Pd nanocluster (NC) film, a metal–organic framework (MOF), and a polymer, are proposed. The polymer coating, as a protection...
Inspired by the stomata of plant leaves, Naien Shi, Yue Lin, Min Han, and co‐workers fabricate 2D Cu‐N‐C nanodisks with stomata‐like interconnected hierarchical porous topology by etching Cu‐tetrapyridylporphyrin (TPyP)‐metal–organic frameworks carbonization product (Cu@Cu‐N‐C) in article number 1902410. Such nanodiscs manifest superior oxygen reduction reaction performance, outperforming Cu@Cu‐N‐C,...
Metal,N‐codoped carbon (M‐N‐C) nanostructures are promising electrocatalysts toward oxygen reduction reaction (ORR) or other gas‐involved energy electrocatalysis. Further creating pores into M‐N‐C nanostructures can increase their surface area, fully expose the active sites, and improve mass transfer and electrocatalytic efficiency. Nonetheless, it remains a challenge to fabricate M‐N‐C nanomaterials...
As one class of important functional materials, transition metal phosphides (TMPs) nanostructures show promising applications in catalysis and energy storage fields. Although great progress has been achieved, phase‐controlled synthesis of cobalt phosphides nanocrystals or related nanohybrids remains a challenge, and their use in overall water splitting (OWS) is not systematically studied. Herein,...
Utilizing pre‐synthesized supramolecular gels and a controllable thermal conversion technique, Yue Lin, Min Han, and co‐workers prepare three kinds of cobalt phosphides nanocrystals encapsulated by P‐doped carbon (PC) and “married” with P‐doped graphene (PG) nanohybrids. Compared with their pure phase counterparts, the mixed‐phase nanohybrids manifest better electrocatalytic performance toward overall...
3D porous nanoarchitectures derived from SnS/S‐doped graphene hybrid nanosheets are successfully prepared by controllable thermal conversion of oleylamine‐capped mixed‐phase SnS2‐SnS nanodisks precursors, and employed as electroactive material to fabricate flexible, symmetric, all‐solid‐state supercapacitors. The fabricated solid devices exhibit very high areal specific capacitance (2.98 mF cm−2),...
By utilizing the promotion effect of the SnS2 component and the redox or thermal stress driven self‐assembly process, in article number 1603494, Qi Wang, Min Han, and co‐authors, successfully prepared novel three‐dimensional (3D) porous hybrid nanoarchitectures (PHNAs) that are derived from SnS/S‐doped graphene nanosheets. Such 3D PHNAs can be used to fabricate high‐performance, flexible all‐solid‐state...
