“…It is expected to achieve a carbon-neutral cycle and alleviate the greenhouse effect and energy crisis by transforming CO 2 into available chemical fuel through solar photocatalytic technology. [7][8][9][10][11][12][13][14][15] Most of the existing photocatalysts are difficult to fully absorb and utilize visible light. Besides, the potentials at the band edge positions are difficult to meet the potential requirements of photocatalytic reaction at the same time, and the photogenerated carrier separation is poor.…”

It is still challenging to design a stable and efficient catalyst for visible‐light CO2 reduction. Here, Er3+ single atom composite photocatalysts are successfully constructed based on both the special role of Er3+ and the special advantages of Zn2GeO4/g‐C3N4 heterojunction in the photocatalysis reduction of CO2. Especially, Zn2GeO4:Er3+/g‐C3N4 obtained by in situ synthesis is not only more conducive to the tight junction of Zn2GeO4 and g‐C3N4, but also more favorable for g‐C3N4 to anchor rare‐earth atoms. Under visible‐light irradiation, Zn2GeO4:Er3+/g‐C3N4 shows more than five times enhancement in the catalytic efficiency compared to that of pure g‐C3N4 without any sacrificial agent in the photocatalytic reaction system. A series of theoretical and experimental results show that the charge density around Er, Ge, Zn, and O increases compared with Zn2GeO4:Er3+, while the charge density around C decreases compared with g‐C3N4. These results show that an efficient way of electron transfer is provided to promote charge separation, and the dual functions of CO2 molecular activation of Er3+ single atom and 4f levels as electron transport bridge are fully exploited. The pattern of combining single‐atom catalysis and heterojunction opens up new methods for enhancing photocatalytic activity.

“…Among them, MOF can be as a new class of porous carrier materials for applications in various elds owning to its permanent porosity, high specic surface area, and diverse functionality structure. [24][25][26][27] Masoumi et al had prepared the PTA/MIL-53 (Fe) composite through the encapsulation method, and it can be as a good adsorbent for tetracycline hydrochloride removal. 28 Wang et al developed a composite material (HPMo@UiO-66) for oxidative desulfurization, and it exhibited excellent catalytic performance.…”

“…In this case, as an alternative sustainable method, the use of free and abundant solar energy for photocatalytic reduction of CO 2 is very attractive. Iron-based metal-organic framework materials are very promising catalysts in the field of photocatalysis, thanks to their large surface area 10 , adjustable structure 11 , high porosity 12 , adjustable light collection capacity in a wide range and uniformly distributed catalytic activity sites and their accessibility to catalysis [13][14] . However, the poor stability of the metal-organic framework itself is an important reason for limiting the photocatalytic activity.…”

In this paper, we prepared a polyvinyl alcohol-polyethylene (PVA-Co-PE) composite nanofiber membrane catalyst decorated by Fe-MOFs/SiC and completed the photocatalytic reduction of CO2 performance. The results show that the CO2 conversion rate of composite film materials under visible light irradiation is increased by 31 times compared with powdered Fe-MOFs/SiC materials. Through SEM, XRD, BET, FTIR, DRS and other characterization methods, the influencing factors of the photocatalytic CO2 reduction process of the composite nanofiber membrane were investigated. The synergistic effect of Fe-MOFs/SiC and nanofiber membrane photocatalysis is beneficial to electron-hole pairs. The effective separation and strong absorption in the visible light region make it exhibit excellent photocatalytic activity in the photocatalytic CO2 reduction reaction.
