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)
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。
