“…In this direction, Sn (which is at least 3 orders of magnitude more abundant than Pt) SAs were embedded homogeneously into a carbon matrix, where each Sn atom coordinated with two O and two C atoms, forming Sn−O−C and Sn−C bonds. 48 The Sn SA carbon anode exhibited enhanced lithium storage capability, in comparison with both the carbon alone and the carbon with embedded SnO 2 nanoparticles, and excellent cyclic stability with a capacity of 478 mAh g −1 at 0.05 A g −1 after 100 cycles and 281 mAh g −1 at 1 A g −1 after 7000 cycles. Apart from lithium-ion batteries, lithium-metal batteries are of broad practical interest in view of their particularly improved theoretical specific capacity of 3860 mAh g −1 , accompanied by the lowest electrochemical potential of 3.04 V vs standard hydrogen electrode (SHE).…”

Anthropogenic activities related to population growth, economic development, technological advances, and changes in lifestyle and climate patterns result in a continuous increase in energy consumption. At the same time, the rare metal elements frequently deployed as catalysts in energy related processes are not only costly in view of their low natural abundance, but their availability is often further limited due to geopolitical reasons. Thus, electrochemical energy storage and conversion with earth-abundant metals, mainly in the form of single-atom catalysts (SACs), are highly relevant and timely technologies. In this review the application of earth-abundant SACs in electrochemical energy storage and electrocatalytic conversion of chemicals to fuels or products with high energy content is discussed. The oxygen reduction reaction is also appraised, which is primarily harnessed in fuel cell technologies and metal-air batteries. The coordination, active sites, and mechanistic aspects of transition metal SACs are analyzed for two-electron and four-electron reaction pathways. Further, the electrochemical water splitting with SACs toward green hydrogen fuel is discussed in terms of not only hydrogen evolution reaction but also oxygen evolution reaction. Similarly, the production of ammonia as a clean fuel via electrocatalytic nitrogen reduction reaction is portrayed, highlighting the potential of earth-abundant single metal species.

“…Besides, the O 1s peak of Cs 2 SnBr 6 /rGO composite moves toward lower binding energy compared with that in GO, which is attributed to the increase of electron cloud density between C and O atoms, and the electron cloud biases from Sn to O as a result of the higher electronegativity of C compared with Sn, resulting in fast electrons transfer in the SnÀ OÀ C structure. [52][53][54] Combined with these changes of different elements, GO is photoreduced to rGO and bonded to Cs 2 SnBr 6 perovskite through chemical bonding SnÀ OÀ C.…”

Severe poisonousness and prolonged instability existing in organic‐inorganic lead‐based perovskite are two matters seriously hindering its potential future application in photocatalysis. Therefore, it is particularly important to explore ecology‐friendly, air‐stable and highly active metal‐halide perovskites. Herein, a new and stable lead‐free perovskite Cs2SnBr6 decorated with reduced graphene oxide (rGO), is synthesized and employed in the photocatalytic organic conversion. The as‐prepared Cs2SnBr6 is ultrastable, exhibiting no clear changes after being placed in the air for six months. The Cs2SnBr6/rGO composite shows excellent photocatalytic activity in photo‐driven‐oxidation of 5‐hydroxymethylfurfural (HMF) to high value enclosed 2,5‐diformylfuran (DFF), achieving>99.5 % conversion of HMF and 88 % DFF selectivity in the presence of green oxidant O2. Comprehensive characterizations disclose a multistep reaction mechanism, demonstrating that the molecular oxygen, photogenerated carriers, ⋅O2− and 1O2 altogether synergistically participate in the effective photo‐driven conversion of HMF to DFF. This work expands the material gallery towards selective organic conversion and environmentally friendly perovskite options for photocatalytic application.

In recent years, the emergence of novel two‐dimensional monoelemental materials (Xenes), e.g., graphdiyne, borophene, phosphorene, antimonene, bismuthene, and stanene, has exhibited unprecedented potentials for their versatile applications as well as addressing new discoveries in fundamental science. Owing to their unique physicochemical, optical and electronic properties, emerging Xenes have been regarded as promising candidates in the community of single‐atom catalysts (SACs) as single‐atom active sites or support matrixes, for significant improvement in intrinsic activity and selectivity. In order to comprehensively understand the relationships between structure and property of Xene‐based SACs, this review represents a comprehensive summary from theoretical predictions to experimental investigations. Firstly, theoretical calculations regarding both the anchoring of Xene‐based single‐atom active sites on versatile support matrixes and doping/substituting heteroatoms at Xene‐based support matrixes are briefly summarized. Secondly, controlled synthesis and precise characterization are presented for Xene‐based SACs. Finally, current challenges and future opportunities for the development of Xene‐based SACs are highlighted.This article is protected by copyright. All rights reserved
