“…In conjugation with other photocatalytic materials it can improve the photocatalytic activity in aqueous and gaseous media [8,9]. For instance, ZIF-9 is shown to activate CO2 leading to positive shift in the onset potential in photoelectrochemical CO2 conversion process [10]. This is also evident using carbon aerogel as a substrate [11].…”

# Deceased in late 20152 Graphical abstract Research Highlights1. A new type of ZIF-8/TiO2 core-shell nanocomposite is designed to facilitate not only CO2 adsorption but also its subsequent photoreduction.2. Sequential fluctuation of reactor pressure plays an important role in promoting product desorption and increasing photocatalyst activity.3. This study highlights the significance of engineering variables including mass transfer and reactor design in photocatalytic reactions. Abstract:A new type of zeolitic imidazolate framework ZIF-8/TiO2 nanocomposites was developed for photocatalytic reduction of CO2 to CH4 and CO in a newly designed photoreactor under intentionally controlled pressure swing. The ZIF-8/TiO2 core-shell structure plays an important role in the adsorption of CO2 by ZIF-8 and subsequent in-situ photocatalytic reduction on TiO2. The introduction of pressure change in the reaction system facilitates the adsorption-desorption process of CO2 and reaction products, which 3 consequently led to improved photoreduction performance. This approach highlights the importance of mass transfer and reactor design for improved photoreduction.

“…[254] In another research, the cobalt-containing zeolite imidazolate framework (ZIF9)/Co 3 O 4 nanowire array interface was constructed, which also shows a nearly 100% CO 2 -to-fomate catalytic selectivity in liquid products. [259] This high selectivity is ascribed to the following reasons: 1) preferred binding to CO 2 on ZIF9 than water leads to an enhanced CO 2 surface concentration; 2) CO 2 can be activated after being adsorbed on ZIF9-Co 3 O 4 NWs, which lowers the CO 2 reduction overpotential and increases kinetics of CO 2 reduction than water/proton reduction on the active sites.

Conversion and storage of solar energy into fuels and chemicals by artificial photosynthesis has been considered as one of the promising methods to address the global energy crisis. However, it is still far from the practical applications on a large scale. Nanoarray structures that combine the advantages of nanosize and array alignment have demonstrated great potential to improve solar energy conversion efficiency, stability, and selectivity. This article provides a comprehensive review on the utilization of nanoarray structures in artificial photosynthesis of renewable fuels and high value‐added chemicals. First, basic principles of solar energy conversion and superiorities of using nanoarray structures in this field are described. Recent research progress on nanoarray structures in both abiotic and abiotic–biotic hybrid systems is then outlined, highlighting contributions to light absorption, charge transport and transfer, and catalytic reactions (including kinetics and selectivity). Finally, conclusions and outlooks on future research directions of nanoarray structures for artificial photosynthesis are presented.

In this study, the electrochemical conversion of xylose to δ-valerolactone via carbonyl intermediates is demonstrated. The conversion was achieved in aqueous media and at ambient conditions. This study also demonstrates that the feedstock for production of renewable chemicals and biofuels through electrochemistry can be extended to primary carbohydrate molecules. This is the first report on a one-pot electrochemical deoxygenation of xylose to δ-valerolactone.
