摘要：
微藻是一种丰富的生物有机材料来源，通过光合作用捕获二氧化碳并将其转化为氧气。本研究提出将微藻作为负二氧化碳排放的牺牲剂与传统光催化水裂解过程结合，使用brookite TiO2作为模型光催化剂，是一种新的策略，以最大化绿色氢气生产并将其转化为有价值的产物，如甲烷和一氧化碳。在最佳条件下，该过程在不添加助催化剂时可产生高达0.990 mmol/g·h的氢气，在添加铂（Pt）助催化剂时可达到3.200 mmol/g·h，比无微藻时的产量高13倍。利用微藻进行光催化具有在绿色氢气生产中的巨大潜力，因为它不仅消除了如醇类等有价值的空穴牺牲剂，还产生其他有用的化合物，如CH4和CO。此外，这种可持续的过程在微藻培养过程中促进了二氧化碳的捕获和转化。
英文摘要：
Microalgae are an abundant bioorganic material source and play a significant role in life on Earth by conducting photosynthesis for carbon dioxide (CO2) capture and its conversion to oxygen (O2). In this study, a combination of microalgae as a negative-CO2-emitting sacrificial agent with the traditional photocatalytic water-splitting process using brookite TiO2, as a model photocatalyst, is introduced as a new strategy to maximize green hydrogen (H2) production while converting microalgae to valuable products, like methane (CH4) and carbon monoxide (CO). The process, under optimal conditions, produces up to 0.990 mmol/g.h of H2 without cocatalyst addition and 3.200 mmol/g.h with platinum (Pt) cocatalyst, which is 13 times higher than the production rate without microalgae. The strategy of using microalgae in photocatalysis has high potential in green H2 production, as it not only eliminates valuable hole sacrificial agents, like alcohol, but also produces other useful compounds, like CH4 and CO. Moreover, this sustainable process contributes to CO2 capture and conversion during microalgae cultivation.
