“…The nucleation and growth kinetics of calcium carbonate, as well as the morphology and polymorphism of the obtained precipitate are affected by various parameters [16], for example, temperature [17], pH [18], additives [19][20][21], saturation, stirring conditions [22], solvents [23], etc. In this respect, special attention has been paid to the role of solution parameters (pH, temperature, supersaturation, additives and impurity ions, etc.)…”

In order to apply precipitated calcium carbonate (PCC) in the detergent industry, its ability to deposit calcium ions in hard water is an important process. In this work, the calcium ion deposition in the presence of PCC from different sources is investigated to reveal the influencing factors and mechanism of nucleation and crystal growth of CaCO3. SEM, XRD, Malvern particle size analysis, and calcium electrodes are used to evaluate the effects of PCC morphology, saturation of Ca2+, and PCC additive amount on the deposition behavior of CaCO3. Through SEM and Malvern particle size analysis, it is found that the precipitation of calcium ions is obviously accelerated by PCC acting as seeds. Moreover, calcium ions are effectively adsorbed on (211) crystal facets, thus prismatic and scalenohedral PCC crystals exhibit better adsorption performance than irregular cubic PCC ones. In addition, XRD demonstrates that PCC reduces or even eliminates the formation of crystals such as vaterite, displaying high deposition capacity under complex water conditions (slightly acidic or highly alkaline pH, low magnesium ion concentration (<0.01 M), and temperatures of 0–60 °C), forming thermodynamically stable calcite in water, which significantly controls the instability of the washing process.

At present, the problem of environmental pollution is becoming increasingly serious. It is urgent to develop efficient catalysts to solve these problems. To obtain the functional characteristics of CaCO3 and promote its application in coatings and photo‐catalysis, ZnO/CaCO3 particles are prepared by the solution co‐precipitation method under the mediate of sodium dodecyl sulfate (SDS) through corresponding strategies. The structures and morphologies of samples are characterized by XRD, FT‐IR, SEM, and TEM, respectively. Besides that, the photo‐catalytic property of the desired product is also evaluated. The results indicate that SDS helps to induce the formation of porous structure. Through co‐precipitation, ZnO particles uniformly load on porous calcium carbonate. ZnO/CaCO3 particles are endowed with low‐cost property and high catalytic performance under the synergistic effect of photo‐catalytic properties and absorption abilities. This work established a simple way to produce the composite catalysts with low price and high photo‐catalytic activity.
