“…from the perspective of heterogeneous catalysts, and of course,t he compatibility of heterogeneous catalytic activation with the organic reactionc onditions. [14] Among these properties, halide perovskite materials are potent to induce route 3 directedr eactions, hence are ap romising photocatalyst candidate for photoredox organic synthesis. [11a,b] It is also important to note here that the detailed reaction mechanisms of many heterogeneous photocatalytic organic transformation system are still under active exploration.…”

“…12 Subsequently, these free radicals exhibit highly oxidative capabilities to convert organic substances into carbon dioxide (CO 2 ) and water (H 2 O) directly, resulting in photocatalytic oxidative decomposition of organic pollutants. Some composite photocatalysts, such as semiconductor-based photocatalysts, 13 graphene-based photocatalysts, [14][15][16] gold nanorod-based hybrids 17 and MOF (metal-organic frameworks)based photocatalysts, 18 recently have been developed for photocatalytic oxidative decomposition to solve a range of environmental issues. Tt is important to note that natural minerals can be used as substrates for preparing environmental-friendly photocatalysts.…”

BACKGROUND In order to prepare an environmental‐friendly photocatalyst, natural mineral sericite is used as the substrate of photocatalysts. In this study, the TiO2‐sericite composite materials are synthesized by a facile sol‐gel process, followed via a calcination treatment that can improve the crystallinity of the nano‐sized TiO2. The prepared composites are characterized by XRD, Raman, FTIR, UV‐vis, SEM, and BETanalysis. The effects of the molecular ratio of TiO2 to sericite and the calcination temperature are also examined. RESULTS Sericite is not only served as a substrate for nano‐sized TiO2 to fabricate the micro‐sized composite materials but also affect the formation of different crystalliniteTiO2. The characteristic results show that the addition of sericite can stabilize the crystal phase of TiO2; therefore, the sericite can maintain the crystalline anatase of TiO2 even after the calcination at 700 °C and 900 °C. Accordingly, the adsorption test and the photocatalytic degradation of methylene blue are conducted to verify the photocatalytic performance of the TiO2‐sericite composite materials. It indicates that the synergetic effect of TiO2‐sericite composites can facilitate the photocatalytic degradation of TiO2 accompanied by the initial adsorption of methylene blue by sericite. Based on the presence of various radicals, including ·OH, ·O2−, and 1O2, the mechanism of photocatalytic degradation of methylene blue via TiO2‐sericite composites are successfully proposed. CONCLUSION The excellent activity reveals that TiO2‐sericite composites are with potential employed as ecological‐friendly photocatalysts in the degradation of pollutants. © 2020 Society of Chemical Industry

As one of the world's most produced chemicals, ammonia (NH 3 ) is synthesized by Haber-Bosch process. This century-old industry nourishes billions of people and promotes social and economic development. In the meantime, 3%-5% of the world's natural gas and 1%-2% of the world's energy reserves are consumed, releasing millions of tons of carbon dioxide annually to the atmosphere. The urgency of replacing fossil fuels and mitigating climate change motivates us to progress toward more sustainable methods for N 2 reduction reaction based on clean energy. Herein, we overview the emerging advancement for sustainable N 2 fixation under mild conditions, which include electrochemical, photo-, plasma-enabled and homogeneous molecular NH 3 productions. We focus on NH 3 generation by electrocatalysts and photocatalysts. We clarify the features and progress of each kind of NH 3 synthesis process and provide promising strategies to further promote sustainable ammonia production and construct state-of-the-art catalytic systems.
