The etching process and reactive rate are promoted by adding HF into the nitric acid aqueous solution, the most probable reactions can be described by the following equations16 3Ag + 4HNO3 → 3AgNO3 + 2H2O + NO (1) 4AgNO3 + 2H2O → 4Ag + 4HNO3 + O2 (2) AgNO3 + HF → AgF + ...
AgNO3; NaH2PO4·3H2O; Bi(NO3)3·5H2O; Na2WO4·2H2O; Isopropyl alcohol (IPA); and MG, MB, and RhB were obtained from Sinopharm Chemical Reagent. Ammonium oxalate (AO) was purchased from Xilong Chemical Reagent, while p-benzoquinone (BQ) was obtained from Aladdin. 2.2. Preparation of ...
Synthesis of 1 1 mmol (289 mg) of NaHL was dissolved in 25 mL of methanol, and 2 drops of HNO3 (70%) and 1 mmol (170 mg) of AgNO3 were added, and the system was then stirred for 10 min. After ca. 3 d at room temperature, orange crystals precipitated and were filtered off ...
