Aqueous solutions were kept at constant ionic strength I=3 mol (Na) ClO /kg H O . Experimental results were depicted in Lippmann ( x-x -log ∑K ) diagrams. The solutus was investigated by pH and Cd sensitive electrodes and it turned out that the solid solutions neither dissolved ...
Balance Ca(NO3)2 + K2CO3 = CO3Ca + NO3K Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every elemen...
The NOxstorage and reduction (NSR) catalytic treatment appears to be a promising approach to remove NOxunder the excess oxygen condition12,13. The NSR catalysts generally consist of three major components: precious metal (e.g. Pt, Pd, or Rh), alkali or alkaline earth metal oxide as NOxstora...
To achieve the nano-properties, the dispersing and deagglomeration of solid dry powder is an important application of nanoparticles! We recommend using: 1. If used in the aqueous phase, may use ultrasonic treatment and add proper dispersants to disperse; 2. If used in oil phase, may use ...
Precipitates are the solid products that form in the net ionic reaction.3Co2+(aq)+2PO43-(aq)= Co3(PO4)2(s)has 1 precipitate. Co3(PO4)2(s) Enter an ionic equation (solubility states are optional) to calculate its complete and net ionic equations. ...
CoO-MoO3/gamma-Al2O3 and NiO-MoO3/gamma-Al2O3 catalysts were prepared by the reaction of alpha-boehmite(alpha-AlOOH)with MoO3 in an aqueous paste,followed ... KM Zdrazil - 《Reaction Kinetics & Catalysis Letters》 被引量: 0发表: 2007年 Neutron-diffraction reinvestigation of NiCO3 Com...
We present a novel method to prepare solid H2CO3 by heating CO2/H2O mixtures at high pressure with a CO2 laser. Furthermore, we found that, contrary to present understanding, neutral H2CO3 is a significant component in aqueous CO2 solutions above 2.4 GPa and 110 °C as identified by...
The electrochemical performance of the BIC-Co3O4 electrodes were evaluated in a three-electrode system in aqueous KOH electrolyte as well as in a two-electrode system using an all-solid-state symmetric supercapacitor device. Section snippets Materials synthesis For the synthesis of BIC, 5 g of...
(CE) of 74.9%, which was comparable to that of Co3O4/graphene hybrid electrodes reported previously12,32. The relative low initial CE value may be ascribed to the inevitable formation of a solid electrolyte interface (SEI) film over the electrode during the charge/discharge process, which ...
