Hu Li and <strong>Zhen Fang<\/strong> published a research article in Chemical Engineering Journal about photoelectrochemical C-C bond cleavage of lignin to exclusively produce aromatic carboxylic acids.<\/p>\n<p style=\"text-align: justify;\">Sustainable upgrading of biomass to high-value chemicals is greatly dependent on catalytic C-C\/C-O bond cleavage of high selectivity. Here, an oxidation-enhanced photoelectrochemical protocol was developed to be capable of breaking different types of C-C bonds for efficiently producing aromatic carboxylic acids (85.0-99.8% yields) from lignin. Ni local electronic state of the prepared F-Fe<sub>2<\/sub>O<sub>3<\/sub>-Co:NiO<sub>x<\/sub>H<sub>y<\/sub> with excellent durability could be modulated, and high-valence Ni(\u2163) reactive species played a key role in the oxidative C-C bond scission of various lignin models. In-situ characterization and control experiments indicated that photocatalytic radical and electrocatalytic interface facilitated C-H\/O-H delocalization, contributing significantly to the enhanced oxidation process. In addition, quantum calculations elaborated that photo-excited holes and Ni(\u2163) are key reactive species for enhancive electrocatalytic cleavage of different C-C bonds in lignin to exclusively furnish aromatic carboxylic acids. This research provides a renewable funnel strategy for using solar energy to produce high-value mono-functional products from biomass.<\/p>\n<p>Related results were accepted in Chemical Engineering Journal:<\/p>\n<p style=\"text-align: justify;\">PD Wu, LY Li, Hu Li *, <strong>Zhen Fang<\/strong> *, Interfacial high-valence Ni(IV)-enabled C-H activation for photoelectrochemical C-C bond cleavage of lignin to exclusively produce aromatic carboxylic acids, <strong>2024, 490<\/strong>, 151722. <a href=\"https:\/\/doi.org\/10.1016\/j.cej.2024.151722\">https:\/\/doi.org\/10.1016\/j.cej.2024.151722<\/a>.<\/p>\n<p><strong> <img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-5310\" src=\"https:\/\/woodrefinery.com\/zhenfang\/wp-content\/uploads\/2024\/05\/2024-5-20TOC1wuPD.jpg\" alt=\"\" width=\"1280\" height=\"720\" srcset=\"https:\/\/woodrefinery.com\/zhenfang\/wp-content\/uploads\/2024\/05\/2024-5-20TOC1wuPD.jpg 1280w, https:\/\/woodrefinery.com\/zhenfang\/wp-content\/uploads\/2024\/05\/2024-5-20TOC1wuPD-300x169.jpg 300w, https:\/\/woodrefinery.com\/zhenfang\/wp-content\/uploads\/2024\/05\/2024-5-20TOC1wuPD-1024x576.jpg 1024w, https:\/\/woodrefinery.com\/zhenfang\/wp-content\/uploads\/2024\/05\/2024-5-20TOC1wuPD-768x432.jpg 768w\" sizes=\"(max-width: 1280px) 100vw, 1280px\" \/><\/strong><\/p>\n<p style=\"text-align: center;\">A \u201cfunnel\u201d type strategy for photoelectrochemical lignin high value utilization. \u7528\u4e8e\u5149\u7535\u5316\u5b66\u6728\u8d28\u7d20\u9ad8\u503c\u5316\u5229\u7528\u7684\u201c\u6f0f\u6597\u201d\u578b\u7b56\u7565\u3002<\/p>\n<hr \/>\n<p style=\"text-align: center;\"><strong>\u535a\u58eb\u751f\u5434\u57f9\u680b\u5728\u674e\u864e\u6559\u6388\u548c\u65b9\u771f\u6559\u6388\u7684\u6307\u5bfc\u4e0b\uff0c\u5728\u56fd\u9645\u5b66\u672f\u671f\u520a<\/strong><strong>Chemical Engineering Journal<\/strong><strong>\u53d1\u8868\u8bba\u6587<\/strong><strong>:<\/strong><\/p>\n<p style=\"text-align: center;\"><strong>\u754c\u9762\u9ad8\u4ef7\u954d\uff08<\/strong><strong>IV<\/strong><strong>\uff09<\/strong><strong>C-H<\/strong><strong>\u6d3b\u5316\u4fc3\u5149\u7535\u5316\u5b66<\/strong><strong>C-C<\/strong><strong>\u952e\u88c2\u89e3\u6728\u8d28\u7d20\u4e13\u4e00\u751f\u4ea7\u82b3\u9999\u65cf\u7fa7\u9178<\/strong><\/p>\n<p style=\"text-align: justify;\">\u6700\u8fd1\uff0c\u535a\u58eb\u751f\u5434\u57f9\u680b\u5728\u674e\u864e\u6559\u6388\u548c<strong>\u65b9\u771f<\/strong>\u6559\u6388\u7684\u6307\u5bfc\u4e0b\uff0c\u5728\u56fd\u9645\u5b66\u672f\u671f\u520aChemical Engineering Journal (Q1;
