Database of Cu NP modified Pt/TiO₂ Nanorod Array Photocatalyst for CO₂ Conversion (Cu NP修飾Pt/TiO₂ 奈米柱陣列光觸轉換CO₂資料庫)

Introduction

The "artificial photosynthesis" process that photoconverts water and carbon dioxide into hydrocarbons and oxygen through semiconductor photocatalyst has been successfully demonstrated. Titanium dioxide photocatalyst is one of the common photocatalysts. Surface modification of titanium dioxide photocatalyst with co-catalysts can further increase the conversion efficiency and the selectivity of specific products. Pt and Cu nanoparticles are common co-catalysts of titanium dioxide photocatalyst for CO₂ photocatalytic conversion. In this database, the process parameters for the synthesis of Cu nanoparticles on the surface of the Pt/TiO₂ nanorod array photocatalyst, including reaction time (min) and Cu(NO₃)₂ concentration (10^-5 M) are employed to evaluate the H₂ selectivity (%), CO selectivity (%), CH₄ selectivity (%), and electron consumption rate (nmol/g/h) of the photocatalytic conversion CO₂ through the Cu nanoparticle-modified Pt/TiO₂ nanorod array photocatalyst. The learning process is up to 1,000,000 times, the root mean square (RMS) error is less than 0.0023, and the false rate is less than 0.01.

利用半導體光觸媒為介質，將水與二氧化碳轉換為碳氫化合物與氧氣的「人造光合作用」（artificial photosynthesis）化學製程，已被成功地展示。二氧化鈦光觸媒為常見的光觸媒之一，以其為基礎，進一步以共觸媒進行表面修飾，來增益轉換效能與特定產物的選擇率，也被廣泛地應用於CO₂光催化轉換之相關研究。Pt與Cu奈米粒子為二氧化鈦光觸媒CO₂光催化轉換常見的共觸媒。本資料庫以於Pt/TiO₂奈米柱陣列光觸媒表面合成Cu奈米粒子之製程參數，包含反應時間（min）與Cu（NO₃）₂濃度（10^-5 M），來評估合成之Cu奈米粒子修飾Pt/TiO₂奈米柱陣列光觸轉換CO₂之H₂選擇率（%）、CO選擇率（%）、CH₄選擇率（%）、與電子消耗率（nmol/g/h）。學習程序為1,000,000次，均方根（RMS）誤差小於0.0023，誤率則小於0.01。
