“…To study the influence of temperature on the degree of graphitization and defect structure of the derived materials, we performed Raman spectroscopy analysis on Br-CN-1- T ( T = 450, 550, 650, 750). In Raman spectroscopy analysis, ∼1318 cm –1 corresponds to amorphous carbon (D peak) and ∼1595 cm –1 belongs to graphitized carbon (G peak). − Furthermore, defects in carbon-based nanostructures can be calculated by the intensity ratio of amorphous carbon to graphitized carbon ( I D / I G ). It can be seen from Figure S16 that the I D / I G value dropped sharply from 2.04 to 1.68 as the pyrolysis temperature increased from 450 to 750 °C.…”

The cycloaddition of CO 2 with epoxides driven by light irradiation is an intriguing approach to preparing cyclic carbonates. However, it remains a great challenge to achieve high photocatalytic efficiency in the absence of a cocatalyst. Herein, we explored a metal−organic-framework (MOF)-templated pyrolysis strategy to prepare uniform bromine ions/nitrogen-codoped carbon materials (Br-CN) as low-cost photocatalysts for CO 2 cycloaddition. The optimal catalyst Br-CN-1−550 can be used as a photocatalyst to catalyze CO 2 cycloaddition, remarkably reducing the energy consumption. As a result of its benefits of high photothermal efficiency and rich nucleophilic sites (Br ions), BN-CN-1−550 affords a 9 times higher yield of 4-(chloromethyl)-1,3-dioxolan-2-one than that of the ZIF-8-derived CN under cocatalyst-free conditions and light irradiation (300 mW•cm −2 full-spectrum irradiation, 10 h). This strategy provides a cost-effective way to obtain cyclic carbonate under cocatalyst-free conditions.

Metal–organic frameworks (MOFs) are coordination polymers with high porosity that are constructed from molecular engineering. Constructing MOFs as photocatalysts for the reduction of nitrogen to ammonia is a newly emerging but fast-growing field, owing to MOFs’ large pore volumes, adjustable pore sizes, controllable structures, wide light harvesting ranges, and high densities of exposed catalytic sites. They are also growing in popularity because of the pristine MOFs that can easily be transformed into advanced composites and derivatives, with enhanced catalytic performance. In this review, we firstly summarized and compared the ammonia detection methods and the synthetic methods of MOF-based materials. Then we highlighted the recent achievements in state-of-the-art MOF-based materials for photocatalytic nitrogen fixation. Finally, the summary and perspectives of MOF-based materials for photocatalytic nitrogen fixation were presented. This review aims to provide up-to-date developments in MOF-based materials for nitrogen fixation that are beneficial to researchers who are interested or involved in this field.
