Increasing both clean water and green energy demands for survival development are the grand challenges of our age. Here, we successfully fabricate a novel multifunctional 3D graphene-based catalytic membrane (3D-GCM) with active metal nanoparticles (AMNs) loading simultaneously obtaining purification generation, via "green" one-step laser scribing technology. The as-prepared 3D-GCM shows high porosity uniform distribution AMNs, which exhibits permeated fluxes (over 100 L m-2 h-1) versatile super-adsorption capacities removal tricky organic pollutants from wastewater under ultra-low pressure-driving (0.1 bar). After adsorption saturating, AMNs in actuates advanced oxidization process to self-clean fouled catalysis, restores capacity well next time separation. Most importantly, welding overcomes lateral shear force damaging during long-term Moreover, could emit plentiful hot electrons light irradiation, realizing hydrolysis reactions hydrogen generation. This precision manufacturing technology provides feasible high-efficient robust microreactor sustainable production as well.
