摘要

K/Co共掺杂氮化碳纳米晶体（KCoCN）在不牺牲剂的情况下，实现了可见光驱动的氢气析出（550 μmol/g/h）和糠醇（FFA）氧化成糠酸（FA， 148 μmol转化率89%）。机理研究表明，KCoCN通过空穴驱动自由基机制加速质子还原H2，促进FFA氧化为FA。

K/Co co-doped carbon nitride nanocrystals for efficient hydrogen photosynthesis coupled with furfuryl alcohol oxidation

K/Co co-doped carbon nitride (KCoCN) nanocrystals enable visible-light-driven H₂ evolution (550 μmol g⁻¹ h⁻¹) coupled with furfuryl alcohol (FFA) oxidation to furoic acid (FA; 148 μmol and 89% conversion) without sacrificial agents. Mechanism studies reveal that KCoCN accelerates proton reduction to H₂ and promotes FFA oxidation to FA through a hole-driven radical mechanism.
