“…Simultaneously, the metallic nature of graphene or CNTs efficiently collect photogenerated charges from the semiconductor [ 125 , 126 ]. Photogenerated electrons move by the built-in electrical field from conduction band of semiconductor to CNTs in order to balance Fermi levels, while holes exist in the semiconductor share in redox reaction [ 127 ]. Padmanabhan et al [ 128 ] prepared a study showing that TiO 2 /graphene is more active for photocatalysis than sole TiO 2 .…”

TiO2 has aroused considerable attentions as a promising photocatalytic material for decades due to its superior material properties in several fields such as energy and environment. However, the main dilemmas are its wide bandgap (3–3.2 eV), that restricts the light absorption in limited light wavelength region, and the comparatively high charge carrier recombination rate of TiO2, is a hurdle for efficient photocatalytic CO2 conversion. To tackle these problems, lots of researches have been implemented relating to structural and material modification to improve their material, optical, and electrical properties for more efficient photocatalytic CO2 conversion. Recent studies illustrate that crystal facet engineering could broaden the performance of the photocatalysts. As same as for nanostructures which have advantages such as improved light absorption, high surface area, directional charge transport, and efficient charge separation. Moreover, strategies such as doping, junction formation, and hydrogenation have resulted in a promoted photocatalytic performance. Such strategies can markedly change the electronic structure that lies behind the enhancement of the solar spectrum harnessing. In this review, we summarize the works that have been carried out for the enhancement of photocatalytic CO2 conversion by material and structural modification of TiO2 and TiO2-based photocatalytic system. Moreover, we discuss several strategies for synthesis and design of TiO2 photocatalysts for efficient CO2 conversion by nanostructure, structure design of photocatalysts, and material modification.

“…Moreover, the metal phthalocyanine is found to show signi cantly optimized electronic structure when further combined with carbon materials, which can be attributed to the high speci c surface area, excellent electrical conductivity, chemical stability, and easily adjustable surface chemistry of carbon materials [9,[26][27][28][29][30][31][32][33]. Furthermore, the decorated heteroatoms with lower (B, P, S, and transition metals) or higher (N) electronegativities distinct from that of carbon can polarize adjacent carbon atoms and change the electronic properties of the carbon skeletons [34,35], which will modify the related electrocatalytic performance [36].…”

In recent years, transition metal-nitrogen-carbon (M-N-C) composites are expected to be an alternative to platinum group metal (PGM) among various nonprecious metal catalysts investigated. However, the major challenge comes from insufficient electrocatalytic performance and durability for oxygen reduction reaction (ORR). In addition to the selection of suitable central metal active sites, the electrocatalytic activity and stability of the M-N-C catalysts can be enhanced by adjusting the electronic structure of the catalysts. In this work, M-N-C/F composites were synthesized by loading transition metal phthalocyanine complexes onto pre-fluorinated carbon nanotubes through a simple pyrolysis method. Pyrroline-N(PN) and graphite-N(GN) formed after thermal treatment can act as electron acceptors to modulate their charge distribution on the M-N4 sites, and the use of pre-fluorinated nanotubes also allows for a more controlled introduction of fluoride ions that are well coordinated to transition metals, both of which can modulate and modify the electronic structure of M-N-C catalysts. The obtained manganese phthalocyanine/fluorinated carbon nanotubes at 800°C (MnPc/FCNT800) exhibits a competitive electrocatalytic ORR performance with the half-wave potential (E1/2) of 0.9 V and only 12.1% decay after 20 h long-term chronoamperometry (CA) test in 1.0 M KOH electrolyte, outperforming the commercial Pt/C. Overall, this work paves the way of the electronic structure modification and design of such M-N-C composites for sustainable energy applications.
