Research summary
Work spans the controlled synthesis of single-atom and bimetallic nanocatalysts and their evaluation in electrocatalysis. Isolated Fe single atoms anchored on N-doped porous carbon were shown to function as an efficient oxygen reduction electrocatalyst at 0.85 V with strong methanol tolerance and stability; first-principles calculations attributed the activity to electron transfer from the single Fe site to adsorbed OH species [1]. A core-shell ZIF-8@ZIF-67-derived CoP nanoparticle embedded in N-doped carbon nanotube hollow polyhedra was reported for overall water splitting, maintaining activity across 36 h with negligible potential decay; DFT analysis linked the improvement to electron transfer from the NCNHP support raising d-band states near the Fermi level and strengthening H binding [2]. A Chemical Reviews article catalogues synthetic strategies for single atomic site catalysts (SASC), framing high atom-utilization efficiency and well-defined coordination environments as the basis for the field and surveying preparation routes for highly reactive and stable metal single atoms on diverse supports [3]. Earlier work on green chemistry for nanoparticle synthesis applied the twelve green-chemistry principles to safer, energy-efficient, and less toxic preparation methods, organizing the field around the rational choice of reductants, solvents, and reaction conditions [4]. A review of bimetallic nanocrystals in core/shell, heterostructure, intermetallic, and alloy configurations discussed composition-dependent surface structure and atomic segregation behaviour and contrasted liquid-phase preparation routes with monometallic syntheses, with applications in electronics and catalysis [5]. The role of support defects was examined on TiO2 nanosheets, where Ti-Au-Ti structures formed at defect sites both stabilize Au single atomic sites and lower the catalytic energy barrier by relieving competitive adsorption [6]. Across these studies the recurring methodology combines controlled synthesis of isolated or alloyed metal sites, structural characterization, electrochemical testing, and DFT modelling to relate active-site coordination to catalytic descriptors.
