“…The reason for this phenomenon could be ascribed to the synthesis nanocomposites have an increased visible light response ability, which can improve the photocatalytic activity with the generation of more photoinduced electron–hole pairs. [ 62 ] Moreover, the color variation of a series of G/M101 composites were observed (inset in Figure 5a). It was obvious that bright orange MIL‐101(Fe) sample turned to dark brown as the concentration of GQD increased.…”

Herein, a one‐step solvothermal method that shows incorporation of the graphene quantum dots (GQDs) on Fe‐based metal organic frameworks (MOFs) [MIL‐101(Fe)] to form GQD/MIL‐101(Fe) (G/M101) composites is reported. MIL‐101(Fe) with the sensitization of GQDs could significantly improve the photocatalytic reduction efficiency of CO2 to generate CO. The prepared composites exhibit excellent optical properties and the photocatalytic activity of G/M101 composites is relevant to GQDs ratio. The CO production rate over G/M101‐5% (224.71 µmol h−1 g−1) is 5 times higher than that of MIL‐101(Fe) (46.20 µmol h−1 g−1). The promising photocatalytic activity of G/M101‐5% strongly depends on the beneficial separation and transfer of photoinduced carriers via a charge migration between GQDs and MIL‐101(Fe). The microstructures and interfacial structures of the G/M101‐5% composite demonstrate that GQDs are closely loaded on the surface of MIL‐101 (Fe), and thus favors to the photoreduction according to their sp2 bonding. This work may figure a new way for the synthesis of photocatalysts for the application on carbon stabilization.

“…77 Recently, Wan et al reported a new nanocomposite that combined the advantages of CsPbBr 3 QDs and MOFs, which exhibited dramatically enhanced photocatalytic performance for CO 2 conversion. 78 Nanocomposites featuring different HPs contents were fabricated using a facile ultrasonic hybrid approach for 30 min. While the UiO-66(NH 2 ) MOF was electronegative due to the existence of amino groups, CsPbBr 3 was electropositive, which caused them to interact strongly.…”

Organic–inorganic metal halide perovskites (HPs) have emerged as new frontier materials for optoelectronic and energy applications. In addition to various well‐known applications, such as solar cells, light‐emitting diodes, photodetectors, and resistive switching memories, HPs can be utilized as efficient photocatalysts for numerous electrochemical reactions, including carbon dioxide (CO2) reduction reactions, hydrogen evolution reaction, photosynthesis, and wastewater treatment. However, the use of HPs toward photo‐driven catalysis remains a tremendous challenge owing to their poor stability in polar solvents. Nevertheless, huge progress has been made to counter this critical issue for improving the performance of HPs as efficient photocatalysts in a wide range of applications. In this review, we first introduce the structures and properties of HPs. Next, we highlight the recent approaches on the fabrication of HPs, including thin films and nanostructures. Strategies for implementing HPs in catalysis systems and their working mechanisms are thoroughly summarized and discussed. Lastly, the current challenges and prospects of the application of HPs toward photocatalytic reactions are fully addressed. © 2020 Society of Chemical Industry

“…Similarly, the photocatalytic CO 2 reduction activity of IHPQDs can be also improved by constructing heterostructure. For example, Wan et al prepared the CsPbBr 3 QDs/UiO‐66(NH 2 ) heterostructure by combining the electropositive CsPbBr 3 QDs with the electronegative UiO‐66(NH 2 ) metal‐organic frameworks (MOFs) through the strong electrostatic interaction, and employed the heterostructure as a photocatalyst for CO 2 reduction. It was revealed that the CsPbBr 3 QDs/UiO‐66(NH 2 ) heterostructure could significantly enhance the charge transport and separation process and also make the absorption edge red‐shifted to the visible region compared to the pristine CsPbBr 3 QDs.…”

Inorganic halide perovskite quantum dots (IHPQDs) have recently emerged as a new class of optoelectronic nanomaterials that can outperform the existing hybrid organometallic halide perovskite (OHP), II–VI and III–V groups semiconductor nanocrystals, mainly due to their relatively high stability, excellent photophysical properties, and promising applications in wide‐ranging and diverse fields. In particular, IHPQDs have attracted much recent attention in the field of photoelectrochemistry, with the potential to harness their superb optical and charge transport properties as well as spectacular characteristics of quantum confinement effect for opening up new opportunities in next‐generation photoelectrochemical (PEC) systems. Over the past few years, numerous efforts have been made to design and prepare IHPQD‐based materials for a wide range of applications in photoelectrochemistry, ranging from photocatalytic degradation, photocatalytic CO2 reduction and PEC sensing, to photovoltaic devices. In this review, the recent advances in the development of IHPQD‐based materials are summarized from the standpoint of photoelectrochemistry. The prospects and further developments of IHPQDs in this exciting field are also discussed.
