Titanium dioxide (TiO2) has attracted increasing attention as a candidate for the photocatalytic reduction of carbon dioxide (CO2) to convert anthropogenic CO2 gas into fuels combined with storage of intermittent and renewable solar energy in forms of chemical bonds for closing the carbon cycle. However, pristine TiO2 possesses a large band gap (3.2 eV), fast recombination of electrons and holes, and low selectivity for the photoreduction of CO2. Recently, considerable progress has been made in the improvement of the performance of TiO2 photocatalysts for CO2 reduction. In this review, we first discuss the fundamentals of and challenges in CO2 photoreduction on TiO2-based catalysts. Next, the recently emerging progress and advances in TiO2 nanostructured and hybrid materials for overcoming the mentioned obstacles to achieve high light-harvesting capability, improved adsorption and activation of CO2, excellent photocatalytic activity, the ability to impede the recombination of electrons-holes pairs, and efficient suppression of hydrogen evolution are discussed. In addition, approaches and strategies for improvements in TiO2-based photocatalysts and their working mechanisms are thoroughly summarized and analyzed. Lastly, the current challenges and prospects of CO2 photocatalytic reactions on TiO2-based catalysts are also presented.

Electrochemical carbon dioxide (CO2) reduction is considered to be an efficient strategy to produce usable fuels and overcome the concerns regarding global warming. For this purpose, an efficient, earth abundant, and a low cost catalyst has to be designed. It has been found that graphene‐based materials could be promising candidates for CO2 conversion because of their unique physical, mechanical, and electronic properties. In addition, the surface of graphene‐based materials can be modified by using different strategies, including doping, defect engineering, producing composite structures, and wrapping shapes. In this review, the fundamentals of electrochemical CO2 reduction and recent progress of graphene‐based catalysts are investigated. Furthermore, recent studies on graphene‐based materials for CO2 reduction are summarized.

“…To date, sustainable solar hydrogen (H 2 ) production, which directly produces by utilizing semiconductor photocatalysts, could provide a promising and environmental-friendly approach to solve the worldwide energy issues and reduce the dependence on fossil fuels [1,2]. Particularly, enormous progress has been made in developing a new system of photocatalysts such as transition metal dichalcogenides [3][4][5][6][7][8][9][10][11][12][13][14][15], transition metal oxide (TMOs) [16,17], transient metal sulfides (TMSs), graphitic carbon nitride (g-C 3 N 4 ) [18][19][20][21][22], metal-organic framework (MOFs) [23][24][25], transition metal nitride (TMNs) [26], and transition metal carbide (TMCs) [27][28][29][30] that could efficiently enhance the H 2 production, and readily scale up for commercialization [2].…”

Low dimensional transition metal carbide and nitride (MXenes) have been emerging as frontier materials for energy storage and conversion. Ti3C2Tx was the first MXenes that discovered and soon become the most widely investigated among the MXenes family. Interestingly, Ti3C2Tx exhibits ultrahigh catalytic activity towards the hydrogen evolution reaction. In addition, Ti3C2Tx is electronically conductive, and its optical bandgap is tunable in the visible region, making it become one of the most promising candidates for the photocatalytic hydrogen evolution reaction (HER). In this review, we provide comprehensive strategies for the utilization of Ti3C2Tx as a catalyst for improving solar-driven HER, including surface functional groups engineering, structural modification, and cocatalyst coupling. In addition, the reaming obstacle for using these materials in a practical system is evaluated. Finally, the direction for the future development of these materials featuring high photocatalytic activity toward HER is discussed.
