However, precise regulation of neighboring effects at dual-atom sites to optimize and enhance CO2RR performance remains highly challenging. This review focuses on Fe-, Co-, Ni-, and Cu-based DACs, systematically elucidating how proximity effects modulate reaction intermediates and product selectivity in both homonuclear and heteronuclear systems. The distinct electronic configurations of homonuclear and heteronuclear DACs lead to diversified CO2RR pathways and product distributions. When the two metal atoms are spatially separated, the weakened electronic coupling primarily lowers the energy barrier for C1 intermediates, thereby improving the selectivity toward C1 products. In contrast, a reduced metal–metal distance strengthens interatomic electronic interactions through the formation of N/O-coordinated or direct metal–metal structures, facilitating C─C coupling and thus enhancing C2 product formation. A mechanistic understanding of C─C coupling serves as a fundamental basis for directing CO2RR toward multi-carbon products with higher energy density and practical relevance. Additionally, theoretical investigations provide valuable insights into structure–activity relationships, offering guidelines for the rational design of efficient DACs for CO2RR.","PeriodicalId":100214,"journal":{"name":"Carbon Neutralization","volume":"5 3","pages":""},"PeriodicalIF":12.0,"publicationDate":"2026-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cnl2.70146","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147696396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study introduces an innovative strategy that utilizes the naturally fine particle size and surface-oxidizable properties of silicon cutting waste (SiCW) to synthesize silicon nanowires (SiNWs) via a precisely controlled two-step constant-voltage molten salt electrolysis process. Experimental results indicate that the electrical double-layer effect enhances the ordered deposition of silicon atoms during electrolysis, while the solid–liquid–solid (SLS) mechanism regulates the directional growth of SiNWs by facilitating nucleation and crystal growth. The resulting SiNWs anode demonstrates an exceptionally high initial discharge capacity of 3519.6 mAh·g−¹ at 0.5 A·g−¹, with an initial Coulombic efficiency of 86.7%, while maintaining a reversible capacity of 1071.5 mAh·g⁻¹ after 300 cycles.

Inspired by the d-band center (εd) theory, this study synthesizes oxygen defective W-doped δ-MnO2 (Od-WMO) with a tailored d-band center through a two-step hydrothermal-calcination method to address the above bottlenecks. The results of theoretical calculation demonstrate that synergistic modulation mechanism of tungsten doping and oxygen defects not only promotes the upward shift of the εd of Mn, significantly enhancing the adsorption capacity for Mg2+, but also simultaneously strengthens Mn-O bonds, thereby markedly improving structural stability. Moreover, the synergistic modulation effect of the two also dramatically narrows the band gap, lowers the migration energy barrier, as well as speeds up the dynamics of charge transport/ion diffusion. As expected, Od-WMO demonstrates outstanding structural durability and remarkable storage capacity (185.2 mAh g−1 at 0.1 A g−1). Moreover, 3,4,9,10-perylenetetracarboxylic diimide (PTCDI) as anode to assembled Od-WMO//PTCDI full cell also exhibit a stable working state.

To address these issues, this study presents a self-powered cathodic protection system driven by a triboelectric nanogenerator (TENG) for environmentally friendly corrosion prevention. The system employs a polytetrafluoroethylene particle-copper electrode TENG integrated with a buoy structure to efficiently harvest wave energy. Coupled with integrated rectification and energy management circuits, the system converts irregular, low-frequency wave motion into a stable direct current output, thereby enabling sustained cathodic protection. Under simulated marine conditions, the TENG exhibited an open-circuit voltage (Voc) exceeding 2000 V, a short-circuit current (Isc) of approximately 50 μA, and a maximum power density of 1428 mW·m⁻² at an excitation frequency of 2.0 Hz. Electrochemical analyses confirmed that this self-powered system significantly suppressed steel corrosion, showing a notable negative shift in corrosion potential and a sharp drop in corrosion current density.

This paper reviews recent progress in electrocatalytic CO2-to-syngas conversion via non-precious metal catalysts. Non-precious metal-based materials have the advantages of lower cost, richer raw materials, and broader industrial prospects compared to precious metal materials. Although in most cases the electrocatalytic performance of non-precious metal materials is lower than that of precious metal materials, four typical catalyst design strategies—carbon substrate loading, morphological structure control, elemental doping, and alloy/composite design strategies—were summarized to boost their performance in converting CO2 into syngas. The review also summarizes the current challenges and future directions of catalyst design, aiming to provide new insights into designing advanced non-precious metal materials for effective CO2 to syngas conversion in the future. In addition, the impacts of equipment such as reactors and electrolytes on the overall catalytic performance have been summarized in this review, aiming to promote CO2 conversion efficiency by combining catalyst design and catalytic equipment design and guide practice. This review presents a comprehensive overview of the latest advances in electrocatalytic CO2 to syngas conversion, focusing on non-precious metal catalysts.

Herein, atomic tellurium supported on nitrogen/phosphorus-codoped porous carbon nanofibers (TeNPC) was designed as the host for accommodating metallic K. The uniformly dispersed Te atoms serve as potassiophilic sites, which can effectively reduce the nucleation energy barrier and guide K nuclei formation and growth. The atomic Te not only allows the homogeneous distribution of the electric field but also enhances the binding energy of the host to decrease K+ concentration polarization, inducing smooth K deposition. Additionally, the hierarchical pore structure of TeNPC and the formation of SEI with a KF-rich inner layer contribute to a dendrite-free morphology of K@TeNPC. Consequently, TeNPC enables a low nucleation overpotential (~21 mV at 0.5 mA cm–2 and 1.0 mAh cm–2) and high Coulombic efficiency (~99.8% after 480 cycles) for K deposition/stripping.
