Solar-driven carbon dioxide (CO₂) photoreduction has been considered as an environmentally friendly and promising strategy to utilize solar energy and mitigate the impact of greenhouse effect. Designing novel cost-effective photocatalytic system with high CO₂ molecules adsorption activity is an efficient avenue to enhance CO₂ photoreduction performance. Herein, a series of NH₂-UiO-66/CdIn₂S₄ (NU66/CIS) photocatalysts with different NU66 contents were constructed via facile in-situ hydrothermal route and displayed graceful morphology. According to a series of characterization results, porous octahedron NU66 were deeply anchored on flowerlike 3D-microspheres CIS, and a part of the small-sized CIS were evenly dispersed on the surface of NU66. Without any sacrificial agent, the optimized 8% NU66/CIS heterojunctions still exhibited the satisfactory photocatalytic efficiency for CO₂ conversion, whose CO and CH₄ yields reached up to 11.24 $\text{μ}$ mol g⁻¹ h⁻¹ and 2.92 $\text{μ}$ mol g⁻¹ h⁻¹, respectively, which were 2.87 and 3.31 folds higher than that of pristine CIS. The remarkably boosted activity of NU66/CIS was originated from the high specific surface area and the formation of heterostructure between the well-dispersed NU66 and CIS, which could promote the electron transfer during CO₂ photocatalytic reduction.

太阳能驱动的二氧化碳 (CO ₂ ) 光还原被认为是一种利用太阳能并减轻温室效应影响的环保且有前景的策略。设计具有高CO ₂分子吸附活性的新型低成本光催化系统是提高CO _{2 光}还原性能的有效途径。在此，一系列NH ₂ -UiO-66/CdIn ₂ S ₄(NU66/CIS) 具有不同 NU66 含量的光催化剂是通过简单的原位水热途径构建的，并显示出优美的形态。根据一系列表征结果，多孔八面体NU66深深锚定在花状3D微球CIS上，部分小尺寸CIS均匀分散在NU66表面。在没有任何牺牲剂的情况下，优化的 8% NU66/CIS 异质结仍然表现出令人满意的 CO ₂转化光催化效率，其 CO 和 CH ₄产率高达 11.24$\text{μ}$mol g ^-1 h ^-1和 2.92$\text{μ}$mol g ^-1 h ^-1分别比原始 CIS 高 2.87 和 3.31 倍。NU66/CIS 显着提高的活性源于高比表面积和分散良好的 NU66 和 CIS 之间形成的异质结构，这可以促进 CO ₂光催化还原过程中的电子转移。
