Despite its industrial significance, conventional production methods, particularly the anthraquinone process, face challenges including high energy consumption, safety risks, and environmental concerns. Emerging approaches such as direct synthesis, electrochemical methods, piezocatalysis, plasma, and photocatalysis offer alternative routes, yet limitations such as low selectivity, slow charge transfer, and catalyst instability persist. Carbon quantum dots (CQDs), particularly their heteroatom-doped variants, have recently attracted attention as efficient and environmentally friendly catalysts for H2O2 generation. Owing to their high surface area, tunable electronic structure, abundant functional groups, and excellent charge separation capabilities, they enhance photocatalytic, piezocatalysis, and electrocatalytic H2O2 production. This review examines each H2O2 production route, presenting a systematic analysis of their mechanisms, recent advances, strengths and weaknesses, techno-economic considerations, and key bottlenecks that must be overcome for scale-up. Also, this review describes CQD synthesis methods and properties and critically evaluates the role of CQDs in improving H2O2 generation efficiency. Furthermore, patent and bibliometric analyses are presented to elucidate current research trends and technological developments. By integrating fundamental principles, material innovations, and practical applications, this review provides a valuable resource for advancing CQD-assisted H2O2 production technologies. 000168545 540__ $$9info:eu-repo/semantics/closedAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000168545 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000168545 700__ $$aBakhshi, Ali 000168545 700__ $$aKhosrowshahi, Mobin Safarzadeh 000168545 700__ $$aDolatabadi, Mahdi Davari 000168545 700__ $$aShayesteh, Hadi 000168545 773__ $$g47 (2026), e01852 [76 pp.]$$tSustainable Materials and Technologies$$x2214-9929 000168545 8564_ $$s3699934$$uhttps://zaguan.unizar.es/record/168545/files/texto_completo.pdf$$yVersión publicada 000168545 8564_ $$s2491104$$uhttps://zaguan.unizar.es/record/168545/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000168545 909CO $$ooai:zaguan.unizar.es:168545$$particulos$$pdriver 000168545 951__ $$a2026-02-09-14:43:08 000168545 980__ $$aARTICLE
