Photocatalytic hydrogen production has been considered a promising approach to obtain green energy. Crystalline porous materials have arisen as key photocatalysts for efficient production. Here, we report strategy in situ photodeposit platinum clusters cocatalyst on covalent organic framework, which makes it an photocatalyst light-driven evolution. Periodically dispersed adsorption sites of species are constructed by introducing adjacent hydroxyl group and imine-N the region framework...
Abstract It is a great challenge to design active and durable oxygen evolution reaction (OER) electrocatalysts for proton exchange membrane (PEM) electrolyzer due the high dissolution of in acidic solution. Herein, Nd‐doped RuO 2 (Nd 0.1 x ) developed enhanced 0.5 m H SO 4 solution with an overpotential 211 mV achieve 10 mA cm −2 . The theoretical calculation reveals that improved activity Nd moderate decrease d‐band center energy, which balances adsorption desorption intermediates....
Integrating a molecular catalyst with light harvester into photocatalyst is an effective strategy for solar conversion. However, it challenging to establish crystallized framework well-organized connections that favour charge separation and transfer. Herein, we report the heterogenization of Salen metal complex rigid covalent organic (COF) through linkage light-harvesting unit pyrene photocatalytic hydrogen evolution. The chemically conjugated bonds between two units contribute fast...
Two-dimensional (2D) photocatalytic material is a vital project for modern solar energy conversion and storage. Despite vast family of potential 2D photocatalysts that demonstrated, their commercial applications are severely limited because fast photogenerated electron–hole recombination. Here, based on first-principles, we propose general paradigm to boost the separation photoexcited charge carriers in by stacking engineering. Taking emerging water splitting photocatalyst MoSi2N4 as an...
Imines are important intermediates in drug synthesis. Photocatalytic aerobic oxidative coupling of amines has been considered as a clean and promising way to produce imines attracted great attention. Herein, we designed synthesized novel two-dimensional porphyrin-based covalent organic framework (Por-BC-COF) which adopts an AA stacking mode with excellent crystallinity, high Brunauer-Emmett-Teller surface areas (1200 m2 g-1 ), wide light absorption range (200-1300 nm) good stability variety...

The regulated electronic structure of RuO 2 by the Co 3 O 4 |RuO nanojunction, together with carbon coating layer that acts as chain mail, lead to excellent OER performance (Co )@C.
It is of great importance to promote charge separation in photocatalysts for enhanced photocatalytic activity under visible light irradiation. In this work, a type-II heterostructured photocatalyst was constructed by compositing phosphorus-doped g-C3N4 (P-CN) and Rh-doped SrTiO3 (Rh-STO) via thermal calcination treatment. A series characterizations were conducted investigate the structure P-CN/Rh-STO. found that Rh-STO interacted with situ generated P atoms from decomposition P-CN during...
