本レビューは、太陽光による水素生成とCO2回収・光変換を単一の触媒プラットフォームで同時に実現する統合型光触媒システムの最新動向を2015〜2026年の文献調査に基づき評価する。半導体ヘテロ接合、g-C3N4複合体、LDH、MXene、MOF、ペロブスカイト酸窒化物、単原子触媒などを対象に、バンド構造工学や界面電荷移動が二機能性能を左右することを示す。光腐食、耐久性、生成物選択性、反応器スケール統合が実用化の主要障壁であり、欠陥工学や機械学習支援触媒探索などの将来機会を提示する。
English
This review evaluates integrated photocatalyst systems that couple solar H2 evolution with CO2 capture and photoconversion in a unified platform, based on a 2015-2026 literature survey. It examines heterojunctions, g-C3N4 composites, LDHs, MXenes, MOFs, perovskite oxynitrides and single-atom catalysts, showing band alignment and interfacial charge transfer govern dual-function performance. Photocorrosion, durability, selectivity and reactor-scale integration remain key barriers; defect engineering and ML-assisted discovery are highlighted as future directions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素基本戦略やGX推進法のもとでグリーン水素とCCUSの社会実装を進めており、本レビューは次世代光触媒の設計指針を提供する。ただし開示・会計フレームワークとの直接的な接点は乏しく、技術ロードマップ検討材料としての位置づけが中心となる。
In the global GX context
Globally, this contributes to the science base underpinning hydrogen and CCUS pathways that feature in transition finance and net-zero corporate strategies, though it does not directly engage TCFD/ISSB disclosure frameworks. It is most relevant to R&D and technology-roadmap audiences rather than disclosure practitioners.

📄 Abstract（原文）
The global pursuit of carbon neutrality has accelerated the development of sustainable technologies that simultaneously address clean energy production and greenhouse gas mitigation. Solar-driven hydrogen (H 2 ) production and carbon dioxide (CO 2 ) capture-conversion are widely recognized as complementary approaches; however, most studies and existing reviews have examined these processes independently, resulting in fragmented catalyst design and limited understanding of their synergistic integration. To address this gap, this review critically evaluates the emerging field of integrated photocatalyst systems capable of coupling solar H 2 evolution with CO 2 capture and photoconversion within a unified catalytic platform. A systematic literature survey of peer-reviewed publications published between 2015 and 2026 was conducted using Scopus, Web of Science, ScienceDirect and SpringerLink to assess recent advances in multifunctional photocatalysts. The review examines semiconductor heterojunctions, graphitic carbon nitride (g-C 3 N 4 )-based composites, layered double hydroxides, transition-metal sulfides, MXenes, metal-organic frameworks, perovskite oxynitrides and single-atom catalysts, with emphasis on the roles of band structure engineering, defect modulation, interfacial charge transfer, active-site regulation and surface chemistry in enhancing dual-function catalytic performance. Critical analysis reveals that synergistic band alignment, efficient charge separation and engineered catalytic interfaces are the primary factors governing simultaneous H 2 evolution and CO 2 conversion, whereas photocorrosion, catalyst durability, product selectivity and reactor-scale integration remain the major barriers to practical implementation. Unlike previous reviews that separately address hydrogen evolution or CO 2 reduction, this work establishes a unified framework integrating catalyst design principles, mechanistic insights, quantitative performance comparisons, stability considerations and techno-economic perspectives. Finally, emerging opportunities in defect engineering, operando characterization, machine-learning-assisted catalyst discovery and integrated solar photoreactor design are highlighted to guide the rational development of next-generation photocatalytic systems for sustainable solar fuel production and carbon-neutral energy technologies.
