【摘要】 <正> 近年来,激光诱导复相催化反应引起了人们的重视,该方面的工作已有一些报道,如CWCO₂激光诱导甲酸分子在热铂丝上的分解反应,脉冲CO₂激光诱导BCl₃分子与吸附在钛上的H₂的反应以及NH₃在铂表面的复相氧化反应。Farneth等人曾报道了在红外激光垂直照射灼烧过的铜片时,气相异丙醇分子的复相分解反应。本文以活性氧化铜粉末为催化剂,激光光束平行于催化剂表面辐照（光束不接触催化剂表面）,测定了激光频率,能量密度等多种因素对异丙醇复相反应的影响。更多还原

【Abstract】 The heterogeneous decomposition of 2-propanol in the presence of CuO powderhad been induced by TEA CO₂ laser radiation. Two different reaction channels wereobserved. Yields and branching ratios are quite sensitive to experimental variables,such as the frequency and energy fluence of laser, the distance between the laserbeam and CuO surface and the nature of buffer gas更多还原
