Optimized Adsorption of H and OH over Amorphous SrRuPtOH Nanobelts towards Efficient Alkaline Fuel Cell Catalysis.

PtRu-based catalysts toward hydrogen oxidation reaction (HOR) suffer from low efficiency, CO poisoning and over-oxidation at high potentials. In this work, an amorphization strategy is adopted for preparation of amorphous SrRuPtOH nanobelts (a-SrRuPtOH NBs). The a-SrRuPtOH NBs has optimized adsorption of intermediates (H and OH), increased number of active sites, highly weakened CO poisoning and enhanced anti-oxidation ability owing to the special amorphous structure.

Solvation Effect-Determined Mechanisms of Cation Exchange Reactions for Efficient Multicomponent Nanocatalysts.

Cation exchange (CE) reaction is a classical synthesis method for creating complex structures. A lock of study on intrinsic mechanism limits its understanding and practical application. Using X-ray absorption spectroscopy, we observed that the evolution from Ru-Cl to Ru-O/OH occurs during the CE between KRuCl and CoSn(OH) in aqueous solution, while CE between KPtCl and CoSn(OH) is inhibited due to the failure of structural evolution from Pt-Cl to Pt-O/OH.

Defective ZnInS Nanosheets for Visible-Light and Sacrificial-Agent-Free HO Photosynthesis via O/HO Redox.

HO photosynthesis has attracted great interest in harvesting and converting solar energy to chemical energy. Nevertheless, the high-efficiency process of HO photosynthesis is driven by the low HO productivity due to the recombination of photogenerated electron-hole pairs, especially in the absence of a sacrificial agent. In this work, we demonstrate that ultrathin ZnInS nanosheets with S vacancies (S-ZIS) can serve as highly efficient catalysts for HO photosynthesis via O/HO redox.

Mycorrhizae are ubiquitous symbioses established between fungi and plant roots. Orchids, in particular, require compatible mycorrhizal fungi for seed germination and protocorm development. Unlike arbuscular mycorrhizal fungi, which have wide host ranges, orchid mycorrhizal fungi are often highly specific to their host orchids.
