“…Afterward, 4 mL of the supernatant was mixed with 0.5 mL of 30% H 2 O 2 solution. The as-prepared samples were kept undisturbed for over 24 There are different theories that deal with the change of precursor concentration against reaction time to gain kinetic parameters. According to the discussion in the Supporting Information on different fitting functions to treat precursor reduction kinetics, the reduction of Pd precursor under the conditions of this work is considered as a quasi-first-order reaction.…”

“…As a type of relatively readily available nanomaterials, Pd nanocubes (NCs) have attracted much research interest in areas of preparation, − growth mechanism, , and application. − For instance, Pd NCs with controlled sizes can be synthesized by tuning the concentration of bromide ions, which are regarded to encourage the selective formation of Pd {100} facets. − Studies on how additives impact the result of certain synthetic systems have been well established, but most of them are qualitative or semiquantitative without much in-depth perspective. Under such circumstances, gaps in those familiar research areas are unintentionally created.…”

“…The NENU‐MV‐5 provides extraordinary catalytic properties because of the cooperative effect of the mixed‐valence VV‐O‐VIV sites on polyoxovanadate. Recently, Fu and co‐workers [49] developed a Co‐ZIF supported H 4 SiW 12 O 40 catalyst for the catalytic transfer hydrogenolysis of lignin to low‐molecular‐weight aromatic compounds. The SiW 12 @Pd/Co‐ZIF‐NS catalyst is a solid acid that results from the self‐assembly of cobalt nitrate metal salt, deprotonated organic ligand and the POM.…”

Lignin, an inherently heterogeneous arylpropanoid polymer, presents a unique resource for the sustainable manufacture of aromatic chemicals and fuels. Recently, numerous catalytic strategies for lignin valorization have been explored. Polyoxometalates (POMs), with their distinctive structures enabling control of redox processes in lignin conversion, have been of particular interest. However, a comprehensive assessment of this emerging field of study is currently missing. This paper aims to fill this gap with a detailed review of the use of POMs for catalytic lignin conversion into value‐added compounds. This review delves into various catalytic lignin conversion techniques, including thermal catalysis, electrocatalysis, and tandem processes for lignin separation, depolymerization, and upgrading. Moreover, we highlight innovative investigations utilizing polyoxometalate‐ionic liquids (POM‐ILs), POM‐deep eutectic solvents (POM‐DESs), and solidification or immobilization techniques for POMs as lignin valorization catalysts. Lastly, we discuss the future prospects and challenges in the domain of POM catalytic lignin conversion.

Because of the polymerization structure and inherent inert chemical activity of lignin, it is still challenging to depolymerize lignin to obtain valuable chemicals. Here, we present the FeCl3 promoted photocatalytic depolymerization strategy to realize Cα-Cβ oxidative cleavage of lignin model compounds at room temperature. The method generates benzoic acid and phenol compounds with high yield. In addition, the method is effective for the depolymerization of organosolv lignin and affords the corresponding cleavage products of Cα-Cβ bonds.This strategy provides a method of using economical photocatalyst to depolymerize lignin, and provides a reference for the industrial depolymerization of lignin.
