Abstract Developing highly efficient electrocatalysts based on cheap and earth-abundant metals for CO 2 reduction is of great importance. Here we demonstrate that the electrocatalytic activity manganese-based heterogeneous catalyst can be significantly improved through halogen nitrogen dual-coordination to modulate electronic structure manganese atom. Such an electrocatalyst exhibits a maximum faradaic efficiency 97% high current density ~10 mA cm −2 at low overpotential 0.49 V. Moreover,...
Anatase TiO2 nanosheets supported on reduced graphene oxide (RGO) were synthesized via a one-step, solvothermal method. During the step, (GO) was to RGO, and, subsequently, anatase with 73.7% exposed {001} facets grown in situ surfaces of RGO nanosheets. Compared pure TiO2, RGO/TiO2 hybrid nanocomposite had improved photoactivity as result effective photoinduced electron transfer from acceptor through interfacial interactions. Trapping tests showed that oxidation dye molecules proceeded for...

The development of facile, rapid, low-energy, environmentally benign routes for the synthesis covalent organic frameworks (COFs) is great interest. This study concerns utilization water containing dissolved CO2 as a solvent room-temperature COF. as-synthesized particles, denoted COF-LZU1, combine advantages good crystallinity, nanoscale size, and high surface area, which suggests promising application support heterogeneous catalysts. Moreover, this versatile -assisted method also applicable...
Nano scratch for optical glass BK7 based on the ductile-removal regime was carried out, and influence rule of parameters surface deformation friction characteristic analyzed. Experimental results showed that, with increase normal force, burrs in edge more obvious, velocity, micro-fracture obvious similarly. The residual depth measured by atomic force microscope. experimental also increased linearly while elastic recovery rate decreased. Furthermore, decreased increased. process Berkovich...
With large quantities of poly(ethylene terephthalate) (PET) fibers being used and discarded each year, the chemical recycling PET is far-reaching importance. The metal-based catalysts currently in often lead to metal residues product coloration, which limits industrialization recycling.

Abstract Wind turbine (WT) blade fabrication typically employs thermosetting resins, whose recycling challenges post-retirement have resulted in environmental pressures. Thus, there is an urgent need to develop a low-viscosity, high-performance, and recyclable material with excellent mechanical properties that compatible WT processes, serving as viable alternative traditional epoxy resins. Poly(methyl methacrylate) (PMMA) resin considered promising candidate for replacing However, the of...
