Photoredox catalysis has been prominent in many applications, including solar fuels, organic synthesis, and polymer chemistry. Photocatalytic activity directly depends on the photophysical electrochemical properties of photocatalysts both ground state excited state. Controlling those properties, therefore, is imperative to achieve desired photocatalytic activity. Redox potential one important factor that impacts thermodynamic kinetic aspects key elementary steps photoredox catalysis. In challenging reactions high redox potentials substrates hamper reaction, leading slow conversion. Thus, development with extreme potentials, accompanied by potent reducing or oxidizing power, required execute high-yielding thermodynamically demanding reactions. this review, we will introduce strategies for accessing transformations. These include molecular design preparing photosensitizers are exceptionally strong ground-state excited-state reductants oxidants, highlighting metal-based photosensitizers. We also outline methodological approaches using two-photon activation, combined electrochemical/photochemical generate reagents from precursors have milder potentials.

In this work, different approaches for the direct and indirect electrooxidation of glycerol, a by-product oleochemistry biodiesel production, synthesis value-added products intermediates biofuel/electrofuel were investigated compared. For electrooxidation, metallic catalysts used, whose surfaces modified by promoters or second catalysts. Bi-modified Pt electrodes (Ptx Biy /C) served as model systems promoter-supported electrocatalysis, whereas IrO2 -modified RuO2 studied catalyst combinations, which compared under acidic conditions with respective monometallic (Pt/C, /Ti, /Ti). Furthermore, inorganic halide mediators (chloride, bromide, iodide) organic nitroxyl (4-oxo-2,2,6,6-tetramethyl-piperidin-1-oxyl 4-acetamido-2,2,6,6-tetramethyl-piperidin-1-oxyl) evaluated electrooxidation. These discussed regarding selectivity, conversion, coulombic efficiency electrochemical glycerol oxidation.
