Hierarchically Engineered Transition Metal Electrode for Direct Lithium Extraction From Brine

Carbon Energy, EarlyView.
Carbon‐modified WO3 nanoparticles deliver lithium extraction from simulated brine with Li+ capacity of 3 mmol Li g−1h−1 and 43% recovery efficiency. Reduced graphene oxide enhances charge transport and interfacial stability, while reversible W redox validated by in‐situ spectroscopy, governs lithium intercalation dynamics and structural stability ...

Characterization of ZnO Thin Films Grown by Spray Pyrolysis Using Various Chemical Precursors

, 2010
Zinc oxide (ZnO) has gained much interest recently due to its semiconductivity, optical transparency, and magneto-optic effects. Obtaining p-type ZnO has been a major obstacle to using ZnO in applications such as spintronics.

Sunlight‐Driven Green Synthesis of Platinum Nanoparticles From Double‐Vacancy Halide Perovskite Precursors for Methanol Reforming

Chemistry – A European Journal, EarlyView.
ABSTRACT The development of synthetic procedures for preparing metal nanoparticles with controlled size using sunlight opens new avenues toward more sustainable methods with lower energy consumption. Herein, we propose the use of double‐vacancy halide perovskites as precursors for engineering highly crystalline and small platinum nanoparticles (< 3 nm)

Dataset for 'PrFeO3 photocathodes prepared through spray pyrolysis'

, 2020
PrFeO3 (PFO) has been shown to be an active photochemical water reduction in slurry reactors, but has yet to be shown as a photocathode for photoelectrochemical water reduction, to the best of our knowledge.

A novel bubbling fluid bed reactor for the autothermal pyrolysis of waste plastics

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract A new pilot‐scale fluidized bed reactor operated under continuous conditions was developed and tested for the thermal pyrolysis of high‐density polyethylene (HDPE). The study focused on assessing the reliability and operability of the system under different operating conditions (400–550°C), while monitoring mass and energy balances, product ...
