The quantum-confined electronic structures, ultrahigh surface-to-volume ratios, and interfacial charge dynamics enable efficient activation and transformation of inert carbon feedstocks, such as CO2, into value-added C2+ molecules. Recent breakthroughs in compositional modulation, defect engineering, and controlled lattice coupling have unlocked new pathways for tunable binding energetics, suppressed parasitic reactions, and enhanced multi-electron transfer kinetics. This review systematically addresses advances in 2D/3D-driven catalytic platforms, including TMDs, MXenes, MOFs, COFs, g-C3N4, and emerging layered materials, highlighting engineered hybrid interfaces that integrate the chemical selectivity of 2D surfaces with the structural robustness of 3D supports. Mechanistic insights from electro-, photo-, and bio-assisted catalytic systems are analysed with an emphasis on C-C coupling efficiency, intermediate stabilization, and product branching rules. Critical bottlenecks encompassing durability, systemlevel integration, theoretical uncertainties, and scalable manufacturing are assessed, alongside strategic directions for industrial-grade carbon valorisation. This article aims to chart a forward-looking roadmap toward converting anthropogenic carbon into sustainable fuels and chemicals through atomically precise catalytic design. 2026-02-28T15:00:00Z https://scholar.dgist.ac.kr/handle/20.500.11750/60384 Title: 백금-알칼리토금속 합금을 포함하는 복합체, 이를 포함하는 연료전지 및 수전해 전지 그리고 이의 제조방법 Author(s): Gyan Barimah Caleb; 유종성 https://scholar.dgist.ac.kr/handle/20.500.11750/60333 Title: 질화규소 복합체 및 이의 제조방법 Author(s): 성종훈; 유종성 Abstract: 본 발명은 (S1) 비정질 질화규소 분말 및 환원제 분말을 혼합하는 단계; 및 (S2) 상기 혼합분말을 열처리하여 비정질 질화규소에 함유된 규소의 적어도 일부를 결정화하는 단계;를 포함하는, 질화규소 복합체 제조방법에 관한 것으로, 제조 공정이 간단하고, 저렴한 비용으로 질화규소 복합체를 제조할 수 있으며, 상기 방법으로 제조된 질화규소 복합체는 결정질 부분과 비정질 부분이 공존함에 따라, 리튬 이차전지용 음극으로 사용 시 용량, 율속 특성 및 수명 특성을 향상시킬 수 있다.
