N2 - The advent of nanoscience and technology has ushered in a realm of possibilities in photocatalysis research, offering transformative applications in energy and environmental sustainability. However, the practical utility of unmodified single semiconductor photocatalysts is hampered by limitations such as a restricted absorption spectrum, low intensity, unproductive recombination of photogenerated electrons and holes, and insufficient catalytic active sites. Among the myriad strategies reported in the literature, the construction of semiconductor heterojunctions emerges as exceptionally successful. This review delves into the rational design and development of efficient photocatalysts, focusing on the nuanced suppression of electrons and holes to facilitate enhanced redox reactions. Key elements explored include morphology control, the formation of diverse heterojunctions, the significance of synthesis methods, and the optimization of essential reaction parameters for hydrogen production. Addressing the broader landscape of challenges, the review not only delineates the advantages and limitations of these strategies but also provides practical insights and tips to overcome hurdles encountered during material synthesis and photocatalytic reactions. Through a comprehensive exploration of the intricacies involved, the review serves as a valuable guide for students and newcomers to the subject area. Moreover, this work transcends its immediate scope, offering new ideas, reasoned conclusions, and forward-looking proposals that aim to shape the trajectory of future research. It is not merely a compendium of knowledge but a catalyst that stimulates researchers working within the field and across interdisciplinary domains. As we navigate the intricate interplay of electrons and holes at the heterojunction interface, this review charts a course toward innovative solutions, ultimately propelling the field of photocatalysis into new frontiers.
