specific Embodiment approach 1

[0021] Specific embodiment one: a kind of NH in this embodiment 2 - The preparation of the UIO-66@TpPa-1 composite was accomplished as follows:

[0022] 1. NH 2 - Preparation of UIO-66;

[0023] 2. NH 2 -Preparation of UIO-66@TpPa-1 composite: NH 2 -UIO-66, 1,3,5-trialdehyde phloroglucinol and p-phenylenediamine were added to a heat-resistant glass tube, followed by 1,3,5-trimethylbenzene and 1,4-dioxane The mixed solution of acetic acid and acetic acid is ultrasonically treated at an ultrasonic frequency of 35~45KHz for 20~30min, degassed by three freeze-thaw cycles in a liquid nitrogen bath, sealed and heated at 120°C for 24~96h, filtered and washed with tetrahydrofuran Three times, dry to get NH 2 - UIO-66@TpPa-1 composite material;

[0024] NH mentioned in step 2 2 - The mass ratio of UIO-66, 1,3,5-trialdehyde phloroglucinol and p-phenylenediamine is 1:1.15:0.85;

[0025] The volume ratio of 1,3,5-trimethylbenzene, 1,4-dioxane and acetic acid in step 2 is 1:1:0.33;...

Abstract

The invention relates to preparation of a composite material NH2-UIO-66@TpPa-1 and water-photodecomposed hydrogen production. The novel composite material NH2-UIO-66@TpPa-1 provided by the invention is used for solving the problem of the existing materials for water-photodecomposed hydrogen production that the efficiency of hydrogen production is not high. The preparation method comprises the steps: 1. preparing NH2-UIO-66; and 2. preparing the composite material NH2-UIO-66@TpPa-1. According to the preparation method, the preparation process is simple and effective, the reagent consumption is low, and the yield is high; and the photocatalyst provided by the invention can be used for effectively solving the problem that the water-photodecomposed hydrogen production of the NH2-UIO-66 is low in efficiency. The composite material NH2-UIO-66@TpPa-1 is applied to the field of photocatalytic-hydrolysis hydrogen production; and shown by experiments, the composite material has excellent water-photodecomposed hydrogen production performance, and the hydrogen production rate can reach 164 micromoles / g / h.

Description

technical field [0001] The present invention relates to a kind of NH 2 - Preparation of UIO-66@TpPa-1 composite material and hydrogen production by photolysis of water. Background technique [0002] Since the 21st century, energy shortage and environmental pollution have become common problems faced by people all over the world, and the development of new energy has become an unavoidable topic. Resources such as solar energy and wind energy have been continuously developed and utilized, and hydrogen energy is Large amount, twice the heat output of fossil fuels, clean and pollution-free, and other excellent characteristics have attracted people's attention and research. There are many ways to generate hydrogen energy, such as: hydrogen production from organic waste, continuous large-scale hydrogen production by using microalgae, hydrogen production from plant raw materials, and hydrogen production by photolysis of water, among which solar energy is used to produce hydrogen b...
