An electrocatalytic membrane-assisted process for hydrogen production from H 2 S in Black Sea: Preliminary results

H2S in Black Sea: Turning an environmental threat to an opportunity for clean H2production via an Electrochemical Membrane Reactor. Research progress in H2S-PROTON Project

“…loaded with 250 mg catalyst admixed with an equal amount of quartz, the heating system of the reactor and the gas analysis system (SHIMADZU 14B). The above description of the apparatus and the corresponding experimental conditions are presented in our previous work [8]. In order to evaluate the catalysts at simulated Black Sea conditions, the H 2 S decomposition reaction was examined also in the presence of H 2 O.…”

Fuel Production from Seawater and Fuel Cells Using Seawater

“…[102] Any process developedf or H 2 Sd ecomposition to produce H 2 in Black Sea deep water,w hich is energy intensive, will have substantial equipmenta nd operating costs,h eavily depending on technology and the commercial price of energy. [102] The cost of H 2 from H 2 Si nB lack Sea deep water may gradually shift closert ot hat of H 2 from solar-driven water electrolysis in the long term. [103] Hydrogenp eroxide (H 2 O 2 )i saclean and sustainable energy source,b ecause the decomposition products are only water and oxygen, and H 2 O 2 is produced from water and dioxygen using solar energy.…”

Sol–gel synthesis and characterization of calcium-deficient hydroxyapatite photocatalysts suitable for hydrogen production: influence of the drip rate in the photocatalytic activity

“…Hydrogen itself is not toxic, and its combustion does not create any pollution or greenhouse gases. Currently, there are several techniques to produce hydrogen, such as employing nuclear reactors to energize hydrolysis reactors, combustion of fossil fuels, electrocatalytic processes, electrolysis, thermolysis and photocatalytic water splitting reactions [1][2][3][4][5]. Photocatalysis is considered as a key technology to generate hydrogen fuel, exploiting the absorption and energy conversion mechanisms in irradiated semiconductor materials, to produce hole-electron pairs to split the water molecule, generating (primarily) hydrogen and oxygen; and since the work of Fujishima and Honda [6] on water splitting, thousands of papers have been published on the topic.…”
