“…and zeolites, [59][60][61][62] and suitable minerals [63][64][65] are the most attractive materials for synthesizing adsorbent-photocatalytic composites. Conventional carbonbased compounds such as activated carbon [66][67][68] and carbon black 69,70 have been deeply studied. More advanced structures such as carbon nanobers, 71,72 carbon nanotubes, [73][74][75] fullerenes, [76][77][78] and graphene, [79][80][81] and new morphologies such as nanohorns, 82 nanopetals 83 (Fig.…”

Research on photocatalytic materials has been a field in continuous expansion in the recent decades, as it is evidenced by the large number of articles published every year. So far, more than 190 different semiconductors have been assayed as suitable photocatalysts. To this figure, it is necessary to add the combinations with other functional materials or between different semiconductors, as well as their morphological modifications. Summing up the outcome of these different preparation strategies eventually leads to the enormous number of photocatalytic systems that have been reported in the scientific literature. Dealing with such an amount of information requires updated and educated guidance to select the most significant realizations, and it also calls for critical assessments on how the expectations are being fulfilled. This perspective article intends to assess the state of the art of photocatalysis with regard to materials and systems, considering the well-established results, but also the emerging aspects, and the envisaged new directions of this technology in the near future. In the first part, the most relevant achievements in this area, some of them already in the market while others still in development, will be reviewed according to the current understanding. The second part of the article is devoted to the most innovative and promising photocatalysts and related systems described in the open literature.

“…It is widely accepted that the degradation of pollutants in water proceeds by oxidation either reacting directly with generated holes or indirectly with OH free radicals [19,20]. Moreover, the photocatalytic activity of TiO 2 is often dependent on the nature and density of surface defect sites.…”

As a kind of highly effective, low-cost, and stable photocatalysts, TiO 2 has received substantial public and scientific attention. However, it can only be activated under ultraviolet light irradiation due to its wide bandgap, high recombination, and weak separation efficiency of carriers. Doping is an effective method to extend the light absorption to the visible light region. In this chapter, we will address the importance of doping, different doping modes, preparation method, and photocatalytic mechanism in TiO 2 photocatalysts. Thereafter, we will concentrate on Ti 3+ self-doping, nonmetal doping, metal doping, and codoping. Examples of progress can be given for each one of these four doping modes. The influencing factors of preparation method and doping modes on photocatalytic performance (spectrum response, carrier transport, interfacial electron transfer reaction, surface active sites, etc.) are summed up. The main objective is to study the photocatalytic processes, to elucidate the mechanistic models for a better understanding the photocatalytic reactions, and to find a method of enhancing photocatalytic activities.
