Classical strong metal–support interactions (SMSI), which play a crucial role in the preparation of supported metal nanoparticle catalysts, is one most important concepts heterogeneous catalysis. The conventional wisdom for construction classical SMSI involves redox treatments at high-temperatures by molecular oxygen or hydrogen, sometimes causing sintered nanoparticles before formation. Herein, we report that aforementioned issue can be effectively avoided wet-chemistry methodology. As...
Single-atom introduced carbon nanomaterials show favorable oxygen-reduction reaction (ORR) and oxygen-evolution (OER) performance for renewable energy applications. Nevertheless, the electronic-structure regulation by decorating heterogeneous single-metal-atoms engineering of a single-atom active-sites' microenvironment need to be optimized simultaneously, which is challenging. Herein, we develop an atomic-interfacial-regulation approach fabricate dual single Fe/Co atoms synchronized with...
A strategy for defective/graphitic synergy in heteroatom-interlinked-triggered asphaltene (D/G-HASP) is presented. D/G-HASP reveals outstanding catalytic activities and durability half-cell (ORR/OER) full-cell (zinc–air) reactions.
Constructing Van der Waals heterojunction is a crucial strategy to achieve excellent photocatalytic activity. However, in most heterojunctions synthesized by ex situ assembly, electron transfer encounters huge hindrances at the interface between two components due large spacing and potential barrier. Herein, phosphate-bridged of cobalt phthalocyanine (CoPc)/tungsten disulfide (WS2 ) bridged phosphate (xCoPc-nPO4- -WS2 designed prepared traditional wet chemistry method. By introducing small...
A rarely discussed phenomenon in the realm of photocatalytic materials involves presence gradient distributed dopants and defects from interior to surface. This intriguing characteristic has been successfully achieved case ZnS through incorporation atomic monovalent copper ions (Cu+) concurrent sulfur vacancies (Vs), resulting a photocatalyst denoted as G-CZS1–x. Through cooperative action these Cu Vs, G-CZS1–x significantly extends its photoabsorption range encompass full spectrum (200–2100...
The review highlights charge transfer, improved photocatalytic performance, and possible photocatalysis schemes in TiO 2 -based composites. It also addresses perspectives challenges transfer mechanisms for photocatalysis.
Transition metal carbides, known as MXenes, particularly Ti3C2Tx, have been extensively explored promising materials for electrochemical reactions. However, transition carbonitride MXenes with high nitrogen content reactions are rarely reported. In this work, incorporated Pt-based electrocatalysts, ranging from single atoms to sub-nanometer dimensions, hydrogen evolution reaction (HER). The fabricated Pt clusters/MXene catalyst exhibits superior HER performance compared the...
As the commercial catalyst in propane direct dehydrogenation (PDH) reaction, one of biggest challenges Pt catalysts is coke formation, which severely reduces activity and stability.

As an essential component of single-atom catalysts, support materials determine the dispersion, utilization, and stability single metal atoms. Here, we reported potential defective doped graphene as a catalyst (SAC) for CO2 conversion to formic acid by hydrogenation. The effect was screened based on single-metal atom.
