摘要：Environmental pollution and energy deficiency represent major problems for the sustainability of the modern world. Photocatalysis has recently emerged as an effective and environmentally friendly technique to address some of these sustainability issues,although the key to the success of this approach is dependent on the photocatalysts themselves. Based on their attractive physic chemical properties,including their ultrahigh surface areas,homogeneous active sites and tunable functionality,metal-organic frameworks（MOFs） have become interesting platforms for the development of solar energy conversion devices. Furthermore,MOFs have recently been used in a wide variety of applications,including heterogeneous photocatalysis for pollutant degradation,organic transformations,hydrogen production and CO2 reduction. In this review,we have highlighted recent progress towards the application of MOFs in all of these areas. We have collected numerous reported examples of the use of MOFs in these areas,as well as providing some analysis of the key factors influencing the efficiency of these systems. Moreover,we have provided a detailed discussion of new strategies that have been developed for enhancing the photocatalytic activity of MOFs. Finally,we have provided an outlook for this area in terms of the future challenges and potential prospects for MOFs in photocatalysis.

摘要：We proposed a new approach to construct zeolitic imidazolate frameworks-67 (ZIF-67) powders directly on carbon cloth without any conductive agent and adhesion agent and the ZIF-67 nanoparticles on carbon cloth were successfully converted into hollow Co3O4 nanostructure via a facile calcination process. Compared with original ZIF-67 powders, the Co3O4@CC electrode materials had admirable specific capacitance of 1164.8 F·g^-1 at an area current density of 2.5 mA·cm^-2. Furthermore, the rate performance remained 42.4% of initial value when the current density was increased to 30 mA·cm^-2 and the specific capacitance maintained 93.4% of initial capacity after 5000 cycles at an area current density of 10 mA·cm^-2. This strategy may have potential prospect for the application of MOFs in the energy storage and conversion field.
