Recent Progress on Engineering Highly Efficient Porous Semiconductor Photocatalysts Derived from Metal–Organic Frameworks

Abstract

Highlights In this review, we survey the recent developments in the fabrication of metal–organic framework (MOF)-derived porous semiconductor photocatalysts toward four kinds of energy-/environment-related reactions.A comprehensive summary of highly efficient MOF-derived photocatalysts, particularly porous metal oxides and metal sulfides, and their heterostructures are provided.Enhanced photocatalytic performance achieved with MOF-derived porous heterostructures as the photocatalyst is discussed in detail.

Ultrathin 2D Metal–Organic Framework Nanosheets In situ Interpenetrated by Functional CNTs for Hybrid Energy Storage Device

“…Emerging as a new category of crystalline porous materials with ultrahigh porosity and abundant metal active sites, metal-organic frameworks (MOFs) are assembled by the coordination bond between metal ions and organic ligands, giving the enormous application prospects [20][21][22]. Recently, extensive researches related to transition metal-based MOFs have been demonstrated that they are the appealing candidates for energy conversion and storage [23][24][25]. However, most MOFs electrodes unavoidably suffer from inherently low electrical conductivity and instability, which has greatly thwarted their capacitive performances and rate capacities [26,27].…”

In‐situ Photosynthetic Route to Tailor Point Defects in TiO2(B) Nanosheets for Visible Light‐Driven Photocatalytic Hydrogen Production

“…Photocatalysis with semiconductor materials has attracted considerable interests due to the potential applications in solar fuel production, environmental clean‐up and water purification . During the past decades, several types of oxide‐based photocatalysts such as simple oxides (TiO 2 , ZnO and α‐Fe 2 O 3 , etc.…”

“…Photocatalysts preparation : The TiO 2 (B) nanosheet powders were prepared by following a modified synthetic method reported by Wang et al . Typically, 1 mL of TiCl 4 and 30 mL of ethylene glycol were mixed together followed by addition of 1 mL water.…”
