Construction of bubbles enrichment sites and gas-diffusion-microchannel to assist Cr(VI) electrochemical reduction in a flow-through electrochemical system

A series of four-substituted polyoxometalate-thiacalix[4]arene-based materials for the efficient photocatalytic reduction of Cr(vi)

“…3,4 Thus far, several techniques have been developed to remediate Cr(VI)-polluted water, such as ion exchange, catalysis, adsorption, and electrochemical treatment. [5][6][7][8] Among these methods, photocatalytic Cr(VI) reduction is considered one of the most favored approaches 9 and possesses the benefits of low cost, high efficiency, and no detrimental byproduct formation. 10 Polyoxometalates (POMs), with unique structures and diverse physical and chemical properties, 11 show various applications in catalysis, 12 magnetism, 13 etc.…”
