6 FAQs about [Ammonium sulfide photocell]

Can ammonium sulfite be oxidized photochemically?

They concluded that, under the irradiance of the ultraviolet light, the ions of the sulfite SO 32- could be oxidized photochemically into SO 42-. According to their work, they indicate that, there are two pathways of the photolysis of the ammonium sulfite.

What is photo thermo chemical hybrid system of sulfur ammonia?

Vagia et al. 2017 developed new photo thermo chemical hybrid system of sulfur ammonia. In their experiment the splitting of water mechanism was done by using a solar beam that uses a quantum UV along with the infrared thermal beams in the step of oxygen generation.

What is the photocatalysis activity of NH4 2 SO3?

They found that, the photocatalysis activity of the catalyst used in order to make the hydrogen generation and the oxidation of the ammonia sulfite was noticed to highly depend on the concentration of the (NH 4) 2 SO 3. Maximum hydrogen production is obtained from 1.25 M solution.

What is the pH of ammonium sulfate solution?

It is compared to a work done by Huang et al. (2006a) where a kinetic study took place for an 0.0432 M ammonium sulfite solution, subjected to UV light, at of 50 °C and the volume of the solution was 1500 mL. Initially some ammonium sulfate is present in the solution and its pH is about 7.9.

What are the intrinsic kinetic parameters of photocatalysis of cadmium sulfide?

For the case of photocatalysis, the intrinsic kinetic parameters of photocatalysis of water splitting reaction of ammonium sulfite and water in the presence of cadmium sulfide as a catalyst under solar radiation was inspected by developing MATLAB codes that can predict the kinetics based on the results of experimental work done.

What are the problems in photocatalytic applications of metal sulfides?

However, some problems and challenges remain in the photocatalytic applications of metal sulfides. The most serious problem, particularly for photocatalytic reactions without sacrificial agents, is photocorrosion, whereby the sulfide catalyst may become unstable or even inactive.
