Z‐Scheme Water Splitting Systems Based on Solid‐State Electron Conductors

open access: yesAdvanced Functional Materials, EarlyView.
This review examines the latest advances in Z‐scheme overall water splitting (OWS) systems for solar hydrogen production. These systems consist of suspended or immobilized hydrogen evolution photocatalysts (HEPs) and oxygen evolution photocatalysts (OEPs).

Effect of temperatures and pH values on the hydrochloric dew point corrosion behavior of 20# steel

open access: yes工程科学学报, 2018
Hydrogen dew point corrosion often occurs in the overhead condensing and cooling system of an atmospheric distillation unit at the initial process of petroleum refining because of the formation of a highly suitable corrosive environment.

Investigation the effect of Papaver Rhoeas, Malva Grandfolia, and Carduus Marianus Leaves Extracts on Mild Steel in HCl solution, by using weight loss method and linear polarisation resistance technique [PDF]

open access: yes, 2012
We can say mild steel studied corrodes in hydrochloric acid solutions, and also mild steel corrodes when exposed to a solution of HCl and the rate of corrosion increases as the immersion time increases.

Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

open access: yesAdvanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Study of crevice-galvanic corrosion of aluminum [PDF]

open access: yes, 1967
Corrosion effects of aluminum-copper and aluminum-nickel couples in oxygenated distilled water, and aluminum alloys in oxygenated copper sulfate solution were studied. One of each of the couples had a water tight seal, and showed no substantial corrosion,
