A <italic>Z</italic>-scheme CeO<sub>2</sub>–AgI photocatalyst was successfully fabricated and its photocatalytic mechanism has been unraveled.
Dual-atom-site catalysts (DACs) have emerged as a new frontier in heterogeneous catalysis because the synergistic effect between adjacent metal atoms can promote their catalytic activity while maintaining the advantages of single-atom-site catalysts, such as almost 100 % atomic efficiency and excellent hydrocarbon selectivity. In this study, cobalt-based atom site catalysts with a Co<sub>2</sub> -N coordination structure were synthesized and used for photodriven CO<sub>2</sub> reduction. The res
This work demonstrates a novel strategy for high H<sub>2</sub> production rate from noble metal-free ultrathin MoS<sub>2</sub> nanosheets-decorated CdS nanorods under natural solar light irradiation.
Abstract Engineering the electronic structure of metal, N‐doped carbon catalysts is a potential strategy for increasing the activity and selectivity of CO 2 electroreduction reaction (CO 2 RR). However, establishing a definitive link between structure and performance is extremely difficult due to constrained synthesis approaches that lack the ability to precisely control the specific local environment of MNC catalysts. Herein, a soft‐template aided technique is developed for the first time to
Semiconductor-based photocatalysis is a green method for the removal of toxic organic pollutants by decomposition into harmless products. However, traditional single-component semiconductors are unable to reach high degradation efficiencies due to excessive photo charge carrier recombination. The use of hybrid nanocomposite photocatalysts is a promising strategy for overcoming this problem by reducing recombination as well as ensuring that large amounts of solar energy are harvested. Herein, a n
This work demonstrates few-layered copper doped MoS<sub>2</sub> nanosheets used as efficient cocatalysts on CdS nanorods to achieve ultra-efficient photocatalytic production of H<sub>2</sub> under solar light irradiation.
Abstract Information about temporally varying molecular structure during chemical processes is crucial for understanding the mechanism and function of a chemical reaction. Using ultrashort optical pulses to trigger a reaction in solution and using time‐resolved X‐ray diffraction (scattering) to interrogate the structural changes in the molecules, time‐resolved X‐ray liquidography (TRXL) is a direct tool for probing structural dynamics for chemical reactions in solution. TRXL can provide direct s
