As one of the hydrogen carriers, ammonia has become promising candidate as a reducing agent for implementing hydrogen-based ironmaking to reduce CO2 emissions. On other hand, abundant high combined water (CW) iron ore recently been investigated raw material ironmaking. Goethite (FeOOH), main component high-CW ore, can change porous hematite (Fe2O3) by dehydration, enhancing its reactivity. This...

The present study focuses on the exploration of a synthetic procedure for preparation green silver nanoparticles. Using lactose as reducing agent, reaction mixture containing precursor was exposed to ultrasonic irradiation at ambient temperature and conditions. To optimize synthesis, pH levels concentration were varied. acidic level, no nanoparticles produced since there color change observed a...
