[102] Experiments and theoretical calculations showed that CO* adsorbed stronger than CN, and could be hydrogenated before desorption, which explained why the main products of photocatalytic CO 2 reduction on BOS were CH 4 and CH 3 OH.

2D van der Waals heterojunctions (vdWhs) are a novel type of metamaterial that are flexible, adjustable, and easy to assemble. Using weak van der Waals forces (vdWfs), layered 2D materials can stack freely to form vdWhs with atomic level flat interfaces. By using different 2D materials and specific stacking methods, their unique properties can be organically combined, to exhibit more abundant optical properties. In fact, nanophotonic devices based on 2D vdWhs have developed rapidly and made significant progress. Therefore, the main progress of 2D vdWhs nanophotonic devices in recent years, including the preparation methods of 2D vdWhs and the performance improvements of various nanophotonic devices, is reviewed. Lastly, the prospects of 2D vdWhs nanophotonic devices are discussed.

Over the past few decades, rising global concentrations of carbon dioxide (CO2) produced from excessive consumption of fossil fuels have become the main cause of the greenhouse effect around the world. Converting CO2 into solar fuel through photocatalysis is an effective solution to mitigate the greenhouse effect and energy crisis simultaneously. Increasingly attention has been paid on bismuth‐based photocatalytic CO2 reduction owing to the unique electronic structure of bismuth‐based photocatalysts. In recent years, researchers have made many breakthroughs in the bismuth‐based photocatalytic reduction of carbon dioxide. In this review, we summarize the structure of common bismuth‐based photocatalysts and focus on the recent progress of rational approach for optimizing catalysts loading, including morphology design, component regulation, facet engineering, doping, and defects engineering on the single bismuth‐based photocatalytic system, cocatalyst loading, heterojunction construction, localized surface plasmon resonance, and polarization. Finally, perspectives and opportunities are presented for future trends of CO2 photocatalytic conversion.

Photoreduction of CO 2 without photosensitizers and scavengers runs into the development bottleneck for lack of excellent photocatalysts and ambiguous reduction mechanism. Herein, an ultrathin CoO layer containing Zn-dopants and O-vacancies (V o -Zn-CoO) is designed as an archetype to explore the influence mechanism of Zn on O-vacancies in ultrathin nanolayer for CO 2 photoreduction. DFT calculations illustrate that Zn-dopants not only reduce formation barriers of *COOH and *CO intermediates, but also form π-backbonding with *CO stimulating CH 4 evolution. Finally, V o -Zn-CoO layer significantly enhances CO 2 photoreduction efficiency and CH 4 selectivity with 26.8 µmol g −1 h −1 (63.8%) compared to 7.2 µmol g −1 h −1 (23.6%) for CoO layer with O-vacancies. Moreover, the synergistic effect of Zn and O-vacancies benefits the stability of O-vacancies in photocatalysts, achieving durable photocatalytic performance of V o -Zn-CoO layer. This work manifests that the strategy of metal atoms synergistic O-vacancies is effective to optimize CO 2 photocatalytic efficiency, selectivity, and stability of photocatalyst with O-vacancies.
