Optimization of Adsorption Sites for Selective Hydrobenzoin and Syngas Production in a Single Photoredox Cycle

Advanced Energy Materials, EarlyView.
Efficient C─C coupling hydrobenzoin production and tunable syngas generation via benzyl alcohol oxidation and CO2 reduction is realized by Ni2P/CdS composite in a single photoredox cycle. In situ and ex situ characterizations, along with theoretical calculations, reveal that the active site optimization facilitates intermediate formation and desorption.

Efficient heat integration within discretely heat integrated distillation columns using liquid injection

AIChE Journal, EarlyView.
Abstract Electrification of distillation processes through discretely heat integrated distillation columns (D‐HIDiC) is an effective approach to enhance energy efficiency and lower carbon emissions. For separating systems with high temperature lift, multi‐stage compression and inter‐stage cooling are necessary to link the high‐pressure rectifier and ...
