It is proposed to transform electronic waste into electrocatalytic devices, with the aim of producing nanomaterials and reducing carbon footprint, thus completing a full cycle recycling reusing materials.
The cobalt nanoparticles (NPs-Co) were synthesized and applied in the removal of Cr(VI).The obtained nanomaterials presented magnetic properties characterized by techniques Transmission Electron Microscopy X-ray diffraction.The NPs-Co, with a diameter less than 50 nm, had composition based on metallic oxide.The NPs-Co Cr(VI) being evaluated different parameters such as time equilibrium, initial pH, dose concentration Cr(VI), system temperature.The was favored at lower pH values, about 100%...
In this work, alkaline and nickel-metal hydride spent batteries were used as precursors of metals for the synthesis polymetallic materials.These materials synthesized via chemical reduction.Materials produced from (PM-NiMH) have a nanometric size, whereas (PM-Alk) micrometric size.PM-NiMH consists mainly Ni, Co, Cu PM-Alk Mn Zn.The surface areas PM-NiMH 82 m 2 g -1 109 , respectively.The applied in removal reactive blue dye 4 (RB4).Parameters such initial pH system, dose materials,...
Here, we show that a perylenediimide-incorporated covalent triazine framework (PDI-CTF) leads to an adequate conductive carbon support for copper single-atom catalysts (Cu-SACs), allowing the selective electroreduction of CO2 methanol. CTF-Cu-SACs converted into methanol with faradaic efficiency 72.6% at low overpotential (0.2 V vs RHE). While increasing −0.4 RHE), promoted syngas (CO and H2) production efficiencies 53.2 39.5%, respectively. Moreover, led robust catalytic stability 20 h...
This work presents the determination of amoxicillin (H3Amox+) in capsules by potentiometric titration. An optimized method was done with a standard solution that title NaOH solution. The initial pH 4.35. As expected, first equivalence point not observed, because fraction H3Amox+ about 2.4%. Thus, HCl added to system protonate zwitterion H2Amox± (98%), and then visualize point. Two inflections were one neutralization e second zwitterion. equivalent volumes estimated using derivative method,...
Abstract Here we propose a simple one‐pot solvothermal method to synthesize well‐dispersed CuO catalysts over carbon black surface for application in CO 2 electrolysis. Although simple, the route produced with good performance even lower contents, increasing efficiency of catalytic layer. Films prepared by straightforward dropping on fluorine tin oxide (FTO) substrates were stable (up 30 hours), showing activity reduction reaction (CO RR) and controlling competitive H evolution...
This study investigated the reductive degradation of acetamiprid (5 mg L -1 ) in aqueous medium (at pH 2.0) induced by zero-valent iron (50 mg).The process was monitored using high-performance liquid chromatography (HPLC) to determine rate as a function reaction time, and direct infusion electrospray ionization mass spectrometry (DI-ESI-MS) search for (and potentially characterize) any possible byproducts formed during degradation.The results obtained via HPLC showed that after 60 min,...
