The process enables production of organic phosphonous acids at lower temperature and atmospheric pressure under milder pH conditions for better regioselectivity in hydrophosphorylation and obtain the phosphonous acid with good yield and purity following simple isolation procedure. Phosphonous acids obtained by the process are commercially valuable as effective detergents and wetting agents, lubricants and lubricant additives, plasticizers for plastics and resins, corrosion inhibitors, chemicals including insecticides and pesticides, cobalt extractants and as key intermediates for preparation of commercially important angiotensin converting enzyme (ACE) inhibitors.

The methods can produce graphene quantum dots with a monodisperse size distribution. The graphene quantum dots are produced, via one-pot synthesis, from a graphene source and a strong oxidizing mixture at an elevated temperature. The strong oxidizing mixture can contain one or more permanganates and one or more oxidizing acids. Exemplary permanganates include sodium permanganate, potassium permanganate, and calcium permanganate. Exemplary oxidizing acids include nitric acid and sulfuric acid. The graphene quantum dots can have an average particle size of between about 1 nm and 20 nm and a monodisperse size distribution. For example, the size distribution can have a span about 1 or less and/or a coefficient of variance of about 0.5 or less. About 40% or more of the graphene quantum dots can have a diameter within ±5 nm of the average particle size of the graphene quantum dots.

An oxidization-precipitation reaction is carried out on metal such as Fe(II) and Mn(II) to produce phosphate salt and hydroxide of the metal oxidized e.g. Fe(III) and Mn(III). With overdosed phosphoric acid, hydroxide of the oxidized metal is then converted to a phosphate salt. The invention also provides a method of preparing “wetâ€? phosphate salt nanoparticles and their application in the synthesis of a cathode material. The present invention exhibits numerous technical merits such as lower cost, easier operation, and being environmentally friendly.
