  • aqueous
  • The as-prepared photocatalysts were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), UV-visible absorption spectra, and photoluminescence spectra (PL). With PdS highly dispersed in the CdS nanostructures, the photoactivity was evaluated by hydrogen evolution from aqueous solution containing Na 2 S/Na 2 SO 3 as sacrificial reagents under visible light irradiation.

  • potentials
  • A suitable cocatalyst cannot only promote the separation of photoexcited electrons and holes and suppress their recombination, but also decrease the activation potentials for H 2 evolution [ 13 ]. (hindawi.com)
  • renewable
  • Our results provide new opportunities for the development of renewable and economic hydrogen production technologies,' says the team. (rsc.org)
  • Hydrogen fuel is among the cleanest renewable resource and is the best alternative to fossil fuels for the future. (rsc.org)
  • Hydrogen, as a kind of renewable energy, has attracted more and more attention due to the depletion of fossil fuels and the pollution caused by continuously increasing energy demands [ 1 - 3 ]. (hindawi.com)
  • stellar
  • Owing to the wide range of astrophysical consequences of these events, astronomers now deem supernova research, across the fields of stellar and galactic evolution, as an especially important area for investigation. (jakearchibald.com)
  • This slow progressive conversion of light‐weight hydrogen to fewer nuclei of heavier hydrogen is accompanied by slow changes in other physical factors in the stellar interior and related slow changes in the star's surface conditions. (cliffsnotes.com)
  • In sum, as the hydrogen is consumed in the central core, the stellar photosphere cools slightly and the luminosity increases (in other words, the star drifts rightward and upward across the main sequence band in the HR diagram). (cliffsnotes.com)
  • electroless
  • For example, in metal-assisted chemical (MAC) etching, electroless metal deposition onto Si substrate is most widely used to deposit catalyst layer, which functions as catalyst to provide holes to local region [ 9 ]. (hindawi.com)
  • structural
  • His current research interests are in the structural and functional modelisation of hydrogenases, the design of artificial organometallic proteins and the photo- and electro-production of hydrogen. (rsc.org)
  • morphologies
  • Crystal structures, morphologies, chemical components, and HER performances of each in an alkaline solution were characterized. (mdpi.com)
  • In our work, we have established how the physical properties of BiVO 4 photoanodes affect performance by systematic study of morphologies and chemical surface compositions in combination with photocurrent measurements. (rsc.org)
  • Most notably, optimal morphologies and chemical surface compositions were identified, enabling rational design of more efficient BiVO 4 photoanodes. (rsc.org)
  • Biology
  • He was the world's most famous atheist but realized that evolution could not explain the intricate complexities being revealed by molecular biology today and so abandoned atheism. (vachristian.org)
  • make
  • In due course, when all hydrogen in the core is exhausted, a star must make more dramatic changes in its structure. (cliffsnotes.com)
