Atomic hydrogen (H*) plays a vital role in the synchronous redox of metallic ions and organic mols. However, H* is extremely unstable as it is easily converted to hydrogen. Herein, we designed a novel strategy for the effective stabilization of H* to enhance its utility. The synthesized Pd nanoparticles grown on the defective MoS2 (DMS) of TiO2 nanowire arrays (TNA) (TNA/DMS/Pd) photocathode exhibited rapid Cr(VI) reduction (∼95% in 10 min) and bisphenol A (BPA) oxidation (∼97% in 30 min), with the kinetic constants almost 24- and 6-fold higher than those of the TNA photocathode, resp. This superior performances could be attributed to: (i) the generated interface heterojunctions between TNA and DMS boosted the separation efficiencies of photogenerated electrons, thereby supplying abundant valance electrons to lower the overpotential to create a suitable microenvironment for H* generation; (ii) the stabilization of H* by Pd nanoparticles resulted in a significant increase in the yield of hydroxyl radical (•OH). This research provides a new strategy for the effective utilization of H* toward rapid reduction of heavy metals and synchronous oxidation of the refractory organics This study involved multiple reactions and reactants, such as 4,4′-Methylenediphenol (cas: 620-92-8HPLC of Formula: 620-92-8).
4,4′-Methylenediphenol (cas: 620-92-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.HPLC of Formula: 620-92-8
