Abstract

Development of near-infrared (NIR)-light-driven photocatalytic hydrogen (H₂) production is indispensable for an efficient use of solar energy in a sustainable society. Herein, a strategy is reported for achieving higher quantum yields of NIR-light-driven photocatalytic H₂ production using salts of diprotonated dodecaphenylporphyrin (H₄DPP²⁺(X⁻)₂), showing large saddle distortion as organic photosensitizers and platinum nanoparticles as catalysts. When a perchlorate ion (ClO₄⁻) is employed as a counter ion (X⁻) of H₄DPP²⁺(X⁻)₂, the quantum yield of the photocatalytic H₂ production reaches to 36% by excitation at 750 nm, which is the highest value among those of NIR-light-driven H₂ production reported so far. Such a drastic enhancement of the quantum yield is achieved by selection of X⁻ as an appropriate counter anion of H₄DPP²⁺, judging from second-order rate constants of photoinduced electron transfer (ET) from electron donors to ³(H₄DPP²⁺(X⁻)₂)* and the reorganization energy of ET for H₄DPP²⁺(X⁻)₂.

以双质子化鞍形扭曲卟啉盐为光敏剂的近红外光驱动制氢研究

发展近红外（NIR）驱动的光催化制氢（H2）技术是可持续发展社会中高效利用太阳能的必要条件。本文报道了一种利用双质子化十二苯基卟啉盐（H4DPP2+(X−)2）作为有机光敏剂和铂纳米颗粒作为催化剂实现nir光催化制氢的高量子产率的策略。当高氯酸盐离子（ClO4−）作为H4DPP2+(X−)2的反离子（X−）时，在750 nm激发下，光催化制氢的量子产率达到36%，是目前报道的nir光催化制氢的最高量子产率。从电子供体向3(H4DPP2+(X−)2)*的光诱导电子转移（ET）的二级速率常数和ET对H4DPP2+(X−)2的重组能判断，选择X−作为H4DPP2+的合适的反阴离子，实现了量子产率的大幅提高。
