Biogas is a combustible composed mostly by methane (CH4) and carbon dioxide (CO2). Methane, the main component of biogas, is the responsible for the characteristics of the fuel itself. Greenhouse gases (GHG), including methane, along with global warming and depletion of fossil fuels have become issues of global concern. In the present work, Pt−Fe catalysts supported on γ‐Al2O3 varying the metal load were synthesized, characterized, and applied in the hydrogen production through dry reforming of methane. The synthesized catalysts were extensively characterized by analytical techniques such as X‐Ray diffraction (XRD), thermal gravimetric analysis coupled with differential thermal analysis (DTA/TGA), infrared spectroscopy with Fourier transform (FT‐IR), scanning electron microscopy (SEM), N2 physisorption, X‐ray photoelectron spectrometer (XPS) and high–resolution transmission electron microscopy (HR‐TEM). The results from the catalytic tests exhibited that methane conversion reached values up to 95 % for all studied catalysts. The maximum H2 selectivity was 68 % (973 K) and 55 % (1173 K), for the bimetallic catalysts 0.15 PFAc (0.5 % Pt‐0.15 % Fe wt/Al2O3) and 0.5 PFAc (0.5 % Pt–0.5 % Fe wt/Al2O3) respectively. XPS and HR‐TEM results confirmed the iron‐platinum phase (FePt). Catalyst characteristics such as specific surface area, average crystallite size and morphology showed to play a role in the methane reforming performance.

“…TiN NPs are among the most widely used nanomaterials in optoelectronic devices [24][25][26]. Because the electronic structure of TiN is composed of ionic bonds, covalent bonds, and metal bands, the p-orbital energy level of nitrogen is lower than the Fermi energy level, resulting in movement similar to that of the free electrons of precious metals such as Au and Ag [27,28].…”

We prepared CsPbBr3/ZnO heterojunctions by self-assembling colloidal CsPbBr3 quantum dots (QDs) on the surface of the ZnO film. The fluorescence of CsPbBr3/ZnO heterojunctions was modulated by titanium nitride nanoparticles (TiN NPs) to obtain highly photoluminescent CsPbBr3/TiN/ ZnO heterojunctions. The results showed that when the TiN thickness was 51 nm, the fluorescence of the CsPbBr3/TiN/ZnO heterojunction was enhanced by 3.2 times compared to that of the CsPbBr3/ZnO heterojunction. TiN NPs combined most of the photo-generated electrons with the holes on the surface of the TiN/CsPbBr3heterojunction, which increased the electron transfer rate and reduced non-radiative recombination. This method of enhancing heterojunction fluorescence could provide a new pathway for photovoltaic, light-emitting diode (LED), photodetector, light sensor, and image sensor applications.

Two primary engineering challenges are en route to fabricating high-performance flexible stainless-steel based Cu(In,Ga)(S,Se)2 solar cells; Growing absorbers without contamination from the substrate, and providing alkali dopants to the absorber. The former is chiefly addressed by introducing a barrier layer, and the latter by post-deposition treatment or including dopant-containing layers in the stack. Here we organize these solutions and different approaches in an accessible scheme. Additionally, reports on interaction between contamination and alkali elements are discussed, as is the impact of barrier layer properties on the interconnect technology. Lastly, we make recommendations to consolidate the multitude of sometimes inharmonious solutions.
