Single-atom catalysts (SACs) have become the forefront and hotspot in energy storage and conversion research, inheriting the advantages of both homogeneous and heterogeneous catalysts. In particular, carbon-supported SACs (CS-SACs) are excellent candidates for many energy storage and conversion applications, due to their maximum atomic efficiency, unique electronic and coordination structures, and beneficial synergistic effects between active catalytic sites and carbon substrates. In this review, we briefly review the atomic-level regulation strategies for optimizing CS-SACs for energy storage and conversion, including coordination structure control, nonmetallic elemental doping, axial coordination design, and polymetallic active site construction.

ConspectusLight-driven polymerizations and their application in 3D printing have revolutionized manufacturing across diverse sectors, from healthcare to fine arts. Despite the popularized notion that with 3D printing "imagination is the only limit", we and others in the scientific community have identified fundamental hurdles that restrict our capabilities in this space. Herein, we describe the group's efforts in developing photochemical systems that respond to nontraditional colors of light to elicit the rapid, spatiotemporally controlled formation of plastics.

The integration of ligand-to-metal charge transfer (LMCT) catalytic paradigms with radical intermediates has transformed the selective functionalization of inert C-H bonds, facilitating the use of nonprecious metal catalysts in demanding transformations. Notably, aerobic C-H carbonylation of methane to acetic acid remains formidable due to the rapid oxidation of methyl radicals, producing undesired C1 oxygenates. We present an iron terpyridine catalyst utilizing LMCT to achieve exceptional C2/C1 selectivity through synergistic photoexcitation, methyl radical generation, and carbonylation.

Electrochemical reduction of CO is an efficient strategy for CO utilization under mild conditions. Tin (Sn) single-atom catalysts (SACs) are promising candidates due to their controllable CO/formate generation via asymmetric coordination engineering. Nevertheless, the factors that govern the selectivity remain unclear.

Electrolytic glucose oxidation has garnered great interest in energy-saving hydrogen generation. However, high charge-transfer resistance and inefficient active centers have been recognized as the primary issues for poor electrochemical performance. In this study, for the first time, we offer a novel defect-rich CeO /β-Ni(OH) composite nanosheet-decorated Ni foam electrocatalyst (denoted as Ce@NF-GA), synthesized a unique hydrothermal approach under the co-participation of glycerol and acetic acid.
