Enhanced photocatalytic removal of U(vi) from water using tea waste biochar/g-C3N4/MoS2 Z-scheme composite: synthesis, performance, and mechanistic insights

“…39 Among them, the addition of CO 3 2− decreased the removal efficiency of U( vi ) by approximately 19%, which may be related to the increase in the solution pH due to the addition of CO 3 . 2–40 To summarize, the coexisting metal ions and anions have a minor impact on the photoreduction of U( vi ), even when their concentration is 10 times higher than that of U( vi ), indicating little effect on the removal efficiency of U( vi ). Therefore, it is confirmed that 10%BgM has high anti-interference ability for the removal of U( vi ).…”

“…22 MoS 2 , an n-type semiconductor with a narrow band gap of 1.2-1.9 eV, exhibits excellent conductivity and strong absorption abilities in the visible region. 23,24 In addition, it is worth noting that MoS 2 has the capability of forming heterojunctions with g-C 3 N 4 owing to its distinct band structure and favorable lattice alignment, facilitating the transfer of electrons and holes. The Z-scheme MoS 2 /g-C 3 N 4 heterojunction has been widely utilized in environmental restoration due to its high separation rate of photogenerated carriers, efficient charge transfer, and enhanced visible-light absorption range.…”

Unveiling the antibacterial strategies and mechanisms of MoS2: a comprehensive analysis and future directions

“…8(c), Huang et al employed graphene as a deposition and electron transfer medium to design a Z-scheme LaFeO 3 /MoS 2 /graphene heterojunction, which exhibited outstanding photocatalytic degradation performance. 140 The step-scheme heterojunction is a kind of semiconductor heterojunction that exploits the significant difference in the conduction band or valence band energies between the donor and acceptor materials to generate a strong built-in electric field at the interface. 141 This high built-in electric field creates a potential barrier at the interface which can separate photoexcited carriers and suppress carrier recombination, leading to high efficiency.…”

Enhanced acetone gas sensing performance of ZnO polyhedrons decorated with LaFeO3 nanoparticles

“…LaFeO 3 , a typical ABO 3 -type perovskite-structured material [24], is widely used in photocatalysis [25,26], supercapacitors, and especially in gas sensors [27,28]. LaFeO 3 has good electrical conductivity and structural stability, and has redox properties over a wide temperature range [29,30].…”
