(99%, Alfa Aesar), methylene blue (MB) powder (J. T Baker Chemical Company), and Cobalt (II) nitrate hexahydrate as source for Co(II) ions (99%, Acros Organics B.V.B.A.). All other chemicals are of analytical grade and were obtained from Aldrich Chemical Company (St. Louise, MO...
(400–500,000 Da). X-ray photoelectron spectroscopy (XPS) was performed using a Thermo Fisher ESCALAB 250Xi with a monochromatic Al Kα X-ray source. Raman Analysis (Raman) was carried out on a Laser Micro-Raman Spectrometer (≤10.2/cm/invia reflex) with high-performance grade Leica ...
(EA-1110; Thermo Fisher Scientific) coupled to a Thermo Fisher Scientific MAT 252 isotope ratio mass spectrometer (IRMS). Three laboratory standards (δ13C = −27.57‰, −19.60‰, and 2.52‰) were used for standardization, and the δ13CPDBvalues have uncertainties of <0.2‰ based ...
reagents are extremely toxic and should not be handled at the point-of-testing to prevent contamination of chemicals into the water stream and the response time is very slow19. Thus, the process does not allow for a convenient testing process while in the environmental setting. Unfortunately, de...
The need for greener processes to satisfy the demand of platform chemicals together with the possibility of reusing CO2 from human activities has recently encouraged research on the set-up, optimization, and development of bioelectrochemical systems (BESs) for the electrosynthesis of organic compounds fr...
