In conventional heterogeneous catalytic process, the activation of C-H bond remains a grand challenge. It is even more difficult to activate the inert C-H bond with other functional groups （e.g. OH） in the same molecule, remaining intact [1]. Although the transformation of C1 species （e.g. CO, CO2, CH4 and CH3OH） into C2 molecules （e.g. C2H4, C2HsOH and HOCH2CH2OH） via C-C coupling has been a hot research topic but the yield of aimed product is still needed to be improved. Ethylene glycol （EG） is a versatile chemical with many important applications, in particular for the manufacture of polyesters, predominantly poly（ethylene terephthalate） [2]. Recently, Wang, Deng and co-workers at Xiamen University cleverly designed a new process for the conversion of methanol to ethylene glycol, in which the EG selectivity can reach 90% （Eq. （1）） [3].

Water oxidation is a 4-electron uphill energy process thatlargely limits the overall water splitting reaction thermody-namically and kinetically [1]. Photocurrent measurementis one of the most important approaches to evaluate the per-formance of a photoanode. It has been well realized thatphotocurrent may render exaggerated performance whenphotocorrosion of electrode occurs, such as the case of ZnOand CdS or when sacrificial reagents are present in the elec-trolyte. However, the choice of electrolyte could be anothervery important but easily overlooked issue for the valid in-terpretation of photocurrent.

Hollow spherical titanium dioxide （TiO2） nanoparticles possess unique properties toward energy and environmental applications, because of the intrinsic properties of TiO2 and benefits induced by their hollow structure. A detailed understanding of TiO2 hollow spheres will promote their use in sustainable energy and environmental applications. This perspective details current methods for synthesizing hollow spherical TiO2 nanoparticles, and their performance in dye-sensitized solar cells, photocatalysts, and batteries. This perspective will promote the design and innovative thinking on the application of hollow spherical metal oxide nanooarticles.
