上转换纳米粒子与 TpPa-1-COF 异质结实现可见—近红外光驱动产氢
Rational Design of Vis‐to‐NIR Light Driven Photocatalytic System With Bidirectional Transfer of Charge and Energy for Enhanced Hydrogen Evolution
AI 导读
研究将具备近红外吸收能力的上转换纳米粒子（UCNPs）与可见光驱动的共价有机框架 TpPa-1-COF 复合，构建 Vis-to-NIR 光驱动产氢的杂化异质结构。
推荐理由
上转换纳米粒子与 COF 构建异质结，把 NIR 光转为可见光供 TpPa-1-COF 使用，产氢速率提升 28 倍。
创新点
把上转换纳米粒子与 TpPa-1-COF 组成异质结，使 NIR 光经上转换后被 COF 利用，并在同一界面实现光生电子与能量的双向转移，从而把 COF 的可用光谱从可见区扩展到近红外。
