“…Therefore, in using TiO 2 as the photocatalysts for CO 2 reduction, the structure or the form of the catalysts should be controlled to control the selectivity of the photocatalytic process. Compared to the commercial TiO 2 nanoparticles (P25, Degussa), the band gap of TiO 2 nanotube arrays decreased by approximately 0.2 eV, indicating the redshifted absorption edge and the enhanced photocatalytic activities of TiO 2 nanotube arrays (Ping et al 2013). Mahmodi et al (2013a) fixed TiO 2 on the stainless steel mesh network for photocatalytic reduction of CO 2 under direct UV irradiation.…”

Fossil fuels are currently the major energy source and are rapidly consumed to supply the increasing energy demands of mankind. CO 2 , a product of fossil fuel combustion, leads to climate change and will have a serious impact on our environment. There is an increasing need to mitigate CO 2 emissions using carbon-neutral energy sources. Therefore, research activities are devoted to CO 2 capture, storage and utilization. For instance, photocatalytic reduction of CO 2 into hydrocarbon fuels is a promising avenue to recycle carbon dioxide. Here we review the present status of the emission and utilization of CO 2 . Then we review the photocatalytic conversion of CO 2 by TiO 2 , modified TiO 2 and non-titanium metal oxides. Finally, the challenges and prospects for further development of CO 2 photocatalytic reduction are presented.

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.

“…[18] These forms are reported to allow better separation of the charge carriers and in many cases exhibit improved crystallinity,t hus performing with significantly higher efficiencies. For instance, Ping et al [24] managed to see the production of ethanol and methanolu sing TiO 2 nanotube arrays (TNTs), ar esult mainly attributed to the combination of larger surface area (compared to P25 films) allowing for more reactants to adsorb outside and inside the TNTsw alls and the faster migration of the charge carriers to the surfaceo ft he TNTs. In reference [26], anatase TiO 2 nanorods weres ynthesized and modified with rutile nanoparticles.…”

“…The morphology of the TiO 2 photocatalyst can also affect the efficiency of the process and the products’ distribution. Apart from nanoparticles, many forms of TiO 2 were synthesized and tested in photocatalytic CO 2 reduction, including nanotubes, nanosheets, nanorods, and nanofibers . These forms are reported to allow better separation of the charge carriers and in many cases exhibit improved crystallinity, thus performing with significantly higher efficiencies.…”

Photocatalytic CO conversion to hydrocarbons (sometimes referred to as 'artificial photosynthesis'), which mimics natural photosynthesis with purely inorganic photocatalysts, has the potential to simultaneously combat the energy crisis and the greenhouse effect. In more than half of all reported studies to date, TiO -based materials are used as the photocatalyst. Yet, the reaction conditions and reactor designs employed in previous studies cover a vast range, hindering mutual comparisons of observed activities and selectivity. In this work, a systematic literature study is attempted, including a selection of only such research publications which report experimental conditions of high purity and a proof of the carbon source (blank experiments, CO isotope labelling or stoichiometric O identification) for CO photoreduction. General trends were then detected and discussed, aiming to guide future research to more efficient photocatalytic systems.
