文献上原话是:1.0mL of 37mM of AgNO3,corresponding to 4mg of Ag, was added into the suspension under rapid stirring. Exactly 0.20mL of 1.5M of NaBH4,
which acts as a reducing agent to reduce Ag+ to Ag, was immediately added into the solution and vigorously stirred for at least 30min. The Ag:NaBH4 molar ratio was kept at ～1:8 for all the synthesis.
请教各位老师们，文献中的0.2mL 1.5mol/L
硼氢化钠溶液怎么配制呀？第一次用硼氢化钠，请多多指教。如果控制用量在1g以内的话需要冰水浴吗？怎么控制硼氢化钠的用量啊？查资料说25℃是，溶解度55g/100g
