LnVO4 (Ln=La, Ce, Pr, Nd, etc.)-based photocatalysts: Synthesis, design, and applications.

• The development of LnVO 4 (Ln=La, Ce, Pr, Nd, etc.)-based photocatalysts are systematic studied. • The effects of morphology, doping, phase structure, crystal facet, defect, heterostructure are thoroughly summarized. • Various photocatalytic applications of LnVO 4 -based photocatalysts are presented. • Current issues are discussed and future research directions are provided. LnVO 4 (Ln = La, Ce, Pr, Nd, etc.) is an emerging photocatalyst for solving the energy and environmental crisis, due to its suitable band gap, special valence electronic structure, high thermal, and chemical stability, as well as excellent photocatalytic performance. Although exhibiting great promise, the low solar power employment efficiency of LnVO 4 materials has limited its further development and application. However, recent breakthroughs have been made in both heightening its photocatalysis efficiency and elucidating the essential photocatalytic mechanisms. Therefore, it is important to review and summarize recent research progress on LnVO 4 nanomaterials and their applications. In this review, we systematically report on and examine recent computational and experimental advances in the modification of LnVO 4 -based photocatalysts through morphology adjustment, elemental doping, phase structure modulation, crystal facet modulation, defect modulation, heterostructure, and beyond. Thereafter, we outline current promising photocatalytic applications and discuss challenges/expected upcoming research aims for LnVO 4 -based photocatalysts. Our goal is to furnish guidance for the reasonable design and preparation of highly efficient LnVO 4 (Ln = La, Ce, Pr, Nd, etc.)-based photocatalytic materials for sundry applications.
