In this paper, polydopamine/graphitic carbon nitride (PDA/g-C3N4) has been synthesized by the dopamine (DA) polymerization modification of surface g-C3N4. For a study morphology and optical property catalysts, obtained PDA/g-C3N4 composites were characterized FTIR, XRD, SEM, TEM, BET, XPS, TGA, DRS (diffuse reflectance spectroscopy), photoluminescence, photocurrent generation. Polydopamine (PDA) plays multiple roles as light absorption substance, an electron transfer acceptor, adhesive...

Surface site resulting surface adsorbates affect the band bending/bulk‐to‐surface charge migration processes interfacial electronic structure/interfacial transfer processes. predominantly enclosed {001} facets expose a high density reactive fourfold‐coordinated Ti sites (Ti 4c ) at which CH 3 OH molecules dissociate to form O...
Abstract The rate‐determining process for electrochemical energy storage is largely determined by ion transport occurring in the electrode materials. Apart from decreasing distance of diffusion, enhancement ionic mobility crucial transport. Here, a localized electron enhanced mechanism to promote ultrafast proposed. Theoretical calculations and analysis reveal that highly electrons can be induced intrinsic defects, migration barrier ions obviously reduced. Consistently, experiment results...
Photocatalytic methane combustion is a promising strategy to eliminate at ambient condition, but efficient photocatalysts are still lacking.
