A C3N4-sensitized TiO2 nanotube array-based photoanode was designed and fabricated via the in situ growth of C3N4 on the surface of TiO2 nanotubes. It shows stable and significantly improved PEC activity for hydrogen generation under visible light irradiation with a hydrogen production rate of about 19.1 μmol h(-1) (a Faradaic efficiency of nearly 100%).

Ammonia inhibition of biohydrogen production was investigated in batch and continuous flow reactors with glucose as a substrate. In batch tests, biohydrogen production rate was highly dependent on pH and ammonia (defined as the sum of NH3 of NH4+ species) concentrations above 2 g N/L. At pH = 6.2, the maximum production decreased from 56 mL/h at 2 g N/L to 16 mL/h at 10 g N/L. At pH = 5.2, prod...

background: the first step of solid waste management is identification of its composition and the amount of solid waste production per capita. the aim of this research was to estimate the quantity of solid waste production at mazandaran university of medical sciences and the possibility of recycling. methods: this study was a cross-sectional study. the quantity of solid waste production was mea...

Sediment caps that degrade contaminants can improve their ability to contain contaminants relative to sand and sorbent‐amended caps, but few methods to enhance contaminant degradation in sediment caps are available. The objective of this study was to determine if powered carbon electrodes emplaced within a sediment cap could create a redox gradient and provide electron donor fo...

OBJECTIVE Honey is an effective antiseptic wound dressing, mainly the result of the antibacterial activity of hydrogen peroxide that is produced in honey by the enzyme glucose oxidase. Because the rate of production of hydrogen peroxide is known to vary disproportionately when honey is diluted, and dilution of honey dressings will vary according to the amount of wound exudate, it is important t...

Τhis study focuses on the exploitation of food-industry wastes as a source for hydrogen production. The wastes which were used were out of date solid baby foods at seven different flavors (solid wastes) and a glucose-based syrup (liquid waste). Preliminary batch hydrogen experiments at mesophilic conditions and initial carbohydrates concentration of 5 g/L were performed to assess the hydrogen p...
