Here we present a photoelectrochemical cell with a record high photocurrent density of 19.8 mA cm \u22122 for hydrogen production by utilizing a high-performance organic\u2013inorganic halide perovskite as a panchromatic absorber and lignocellulosic biomass as an alternative source of electrons working at lower potentials. In addition, value-added chemicals such as vanillin and acetovanillone are produced via the selective depolymerization of lignin in lignocellulosic biomass while cellulose remains close to intact for further utilization. This study paves the way to improve solar hydrogen productivity and simultaneously realize the effective use of lignocellulosic biomass.<\/p>\n","protected":false},"excerpt":{"rendered":"<h4>DOI:<\/h4>\n<div class=\"b-doi\">10.1038\/s41467-022-33435-1<\/div>\n<h4>Authors:<\/h4>\n<div class=\"b-author\">Yuri Choi, Rashmi Mehrotra, Sang-Hak Lee, Trang Vu Thien Nguyen, Inhui Lee, Jiyeong Kim, Hwa\u2010Young Yang, Hyeonmyeong Oh, Hyunwoo Kim, Jae\u2010Won Lee, Yong Hwan Kim, Sung\u2010Yeon Jang, Ji\u2010Wook Jang, Jungki Ryu<\/div>\n<h4>Abstract:<\/h4>\n<div class=\"b-intro\">Abstract Solar hydrogen production is one of the ultimate technologies needed to realize a carbon-neutral, sustainable society.
