“…This section describes the general features of the conventional SnO 2 -TiO 2 nanohybrid photocatalysts without atomically commensurate junction (Scheme 1). The photocatalytic activity of TiO 2 can be greatly boosted by coupling with SnO 2 for various reactions [11][12][13][14][15][16][17]. It is worth noting that the electron acceptor in common with these reactions is molecular oxygen.…”

“…From a view of practical point, the SnO 2 -TiO 2 coupling system is a very promising material owing to the robustness, harmlessness, and inexpensiveness. The remarkable SnO 2 -TiO 2 coupling effect on the photocatalytic activity is well recognized for various reactions as reported in recent papers on degradations of phenol [11] and dyes [12][13][14][15]. However, the fundamental mechanism has not been fully understood so far.…”

This review article highlights atom-level control of the heterojunction and homojunction in SnO2-TiO2 nanohybrids, and the effects on the photocatalytic property. Firstly, a comprehensive description about the origin for the SnO2-TiO2 coupling effect on the photocatalytic activity in the conventional SnO2-TiO2 system without heteroepitaxial junction is provided. Recently, a bundle of thin SnO2 nanorods was hetero-epitaxially grown from rutile TiO2 seed nanocrystals (SnO2-NR#TiO2, # denotes heteroepitaxial junction). Secondly, the heterojunction effects of the SnO2-NR#TiO2 system on the photocatalytic activity are dealt with. A novel nanoscale band engineering through the atom-level control of the heterojunction between SnO2 and TiO2 is presented for the photocatalytic activity enhancement. Thirdly, the homojunction effects of the SnO2 nanorods on the photocatalytic activity of the SnO2-NR#TiO2 system and some other homojunction systems are discussed. Finally, we summarize the conclusions with the possible future subjects and prospects.

“…In the application of traditional catalysts, there is a method to control the catalyst activity by treating the induced material itself. A quintessential method is the manufacture of TiO 2 (Chen J. et al, 2020) doped composite semiconductor with good catalytic effect, including but not limited to SnO 2 /TiO 2 (Kusior et al, 2018), WO 3 /TiO 2 (Wang et al, 2019), MoO 3 /TiO 2 (Liu et al, 2016), SiO 2 /TiO 2 (Cui et al, 2019), and ZrO 2 /TiO 2 . The development of 2D material catalysts is similar to that of traditional materials.…”

The successful preparation and application of graphene shows that it is feasible for the materials with a thickness of a single atom or few atomic layers to exist stably in nature. These materials can exhibit unusual physical and chemical properties due to their special dimension effects. At present, researchers have made great achievements in the preparation, characterization, modification, and theoretical research of 2D materials. Because the structure of 2D materials is often similar, it has a certain degree of qualitative versatility. Besides, 2D materials often carry good catalytic performance on account of their more active sites and adjustable harmonic electronic structure. In this review, taking 2D materials as examples [graphene, boron nitride (h-BN), transition metal sulfide and so on], we review the crystal structure and preparation methods of these materials in recent years, focus on their photocatalyst properties (carbon dioxide reduction and hydrogen production), and discuss their applications and development prospects in the future.

“…The design and construction of TiO 2 ‐based photoanodes with high visible light harvesting capability is a major challenge for their commercialization. Strategies in literature can be classified as (i) doping with elements (e. g. C, N, Fe, Ni, and Cu), (ii) constructing heterostructures by means of combining TiO 2 with other semiconductors, (iii) depositing noble metal nanoparticles on the surface of TiO 2 , (iv) controlling morphologies and electronic transmission structures, etc. Furthermore, the anodization strategy has proven to be more effective (Table ) in synthesizing ordered nanomaterials compared to the chemical method.…”

TiO 2 -based photoanodes are very well known for their photoresponse performance, however, their inability to work in the visible range is still a challenge. To tackle this issue, Al-doped or Sn-coupled Ti 3 SiC 2 (Al-TSC or Sn-TSC) is fabricated via a hotpress sintering technique, and the anodized Al-TSC or Sn-TSC is abbreviated as Al-ATSC or Sn-ATSC. The Al-ATSC or Sn-ATSC with optimized doping content of Al or Sn corresponding to a superior photocurrent of 137.24 μA cm À 2 or 126.76 μA cm À 2 which is 18 or 16 times higher than that of the anodized Ti 3 SiC 2 (ATSC) (7.6 μA cm À 2 ) respectively. The capacitance for Al-ATSC or Sn-ATSC samples can be improved in the presence of visible light illumination. Enhanced photoelectrochemical (PEC) mechanism for Al-ATSC is that generated defects in Al doped TiO 2 (Al-TiO 2 ) improve the visible light absorption capacity, for Sn-ATSC is the suppressed recombination of hole-electron pairs by the coupling effect of SnO 2 /TiO 2 .[a] Prof.
