Опубликована: Июль 21, 2020

Abstract Hollow multishelled structures (HoMSs) provide a promising platform for fabricating photocatalysts, because the unique structure optimizes effective surface and mass transport, showing enhanced light absorption, optimized transport highly active sites exposed. Subsequently, rational design on HoMS photocatalytsts is elaborated to boost photocatalytic activity with efforts in all dimensions, from nanoscale microscale. Breakthroughs synthetic methodology of HoMSs have greatly evoked prosperous researches since developing sequential templating approach 2009. The dawn photocatalyst coming after revealing temporal‐spatial ordering property, which also discussed this paper pioneer works demonstrating energy/mass transfer processes. Some insights into key challenges perspectives photocatalysts are discussed. With reviewed fate future hopefully new concepts innovative can be inspired flourish sun‐rise field.
